Review of Megaman

Review Of Megaman Energy Saving Lightbulbs

Find out more about the Megaman range of CFL energy saving lightbulbs


   

In our article Dimmable Energy Saving Lightbulbs we discussed the recent introduction of CFL energy saving lightbulbs which can be used with standard dimmer switches. In order to look in more detail at these bulbs we have conducted in depth reviews of a couple of standard sized lightbulbs from the latest Megaman Dimmable range.

At the same time, we'll have a closer look at a couple of Megaman GU10 compact reflector lightbulbs, designed as direct replacements for standard 50W halogenspotlights.

The Bulbs Under Review


Megaman lightbulbs on review

During this review we will be looking at the following selection of lightbulbs from the Megaman range:

(1) 9 Watt smooth dimming SES E14 candle lightbulb (CL809d) in 2700K warm white. Equivalent to a 45 Watt incandescent. Typically used in chandaliers and similar light fittings with multiple small candle bulbs.
(2) 11 Watt smooth dimming B22 bayonet lightbulb (GSU111d) in 2700K warm white. Equivalent to a standard 60 Watt incandescent light bulb which is probably still the most common light bulb sold in the UK.
(3) 11 Watt GU10 compact reflector lightbulb in 4000K cool white and 3000K warm white versions (BRO711i). Equivalent to the common 50 Watt halogen spotlight bulbs.

All bulbs were tested using a plug-in mains power monitor and the claimed power consumptions of each bulb confimed to be accurate.

The Dimmable Lightbulbs

The two bulbs from the Dimmable range are designed to be used with any standard dimmer switch, and claim to provide smooth dimming through 10%*-100% brightness.
Subject to dimmer specifications.
Megaman 11W dimmable energy saving lightbulb

These bulbs have a very similar shape to their standard incandescent equivalents, and therefore can be used in the full range of attractive light fittings and chandaliers without looking out of place.

When we first tested these bulbs we had a number of compatibility issues with the dimmer switches we used. When the dimmer switch was turned up to full brightness, the light bulbs turned on (after a very short delay) and gave an overall brightness to the room just a little below that from a 60W incandescent (and a bit whiter). As we turned the dimmer down, the brightness level fell very smoothly to approximately half brightness. Below that - as we continued turning the dimmer down - the bulb started to flicker a little, and then started strobing (i.e. flashing on and off many times per second). With the dimmer switch at around 30% the bulb turned off altogether.

However, third time lucky, we found a lighting circuit fitted with a dimmer switch which enabled the bulb to be dimmed from full brightness to approximately 20% brightness before turning off. There was no flickering or strobing whatsoever, and the bulb worked very well. It was also possible to turn the bulb on with the dimmer switch set to very low brightness which is very useful.

We would therefore recommend these bulbs, but with a warning that you should purchase and try just one bulb to see if it will work well with your dimmer switch. Alternatively contact Megamann directly with the manufacturer name and model number for your dimmer switch and they should be able to advise.

One thing to remember is that with any dimmer switch, the amount of electricity consumed is not directly proportional to the brightness of the bulb. For instance, when the bayonet bulb which uses 11 Watts of power at 100% brightness is dimmed to just 10% brightness, it still uses 5 Watts of power (almost 50%). Therefore, you can save electricity and money by dimming your lights, but a more efficient way to save is to fit a lower powered lightbulb in the first place.

The Megaman GU10 Spotlights

The Megaman GU10 spotlights are available in two different colour types - a 3000K warm white, and a 4000K cool white. While we recommend (and sell) a range ofGU10 LED Spotlights they are not as bright as the 50W halogen bulbs they are often destined to replace. In addition, their beam angle is quite narrow compared to that of halogen spotlights, and their colour is a very cool white. Therefore, LED spotlights make fantastic "spotlights", and use just 1 Watt of power, but there are situations (such as general lighting in a large room) when a brighter warmer alternative to LED spotlights is needed.

Pictured above are photographic comparisons of 1 Watt LED spotlights, a standard 50W halogen spotlight, and an 11W warm white Megaman GU10 CFL bulb. It is difficult to see in the photograph, but the halogen definitely had a warmer, more yellow light than the Megaman bulb. The beam angle and overall brightness of the halogen and Megaman bulbs are very similar so the Megaman 11W bulb can indeed be used as a direct 50W halogen replacement. Both of these Megaman bulbs give a room a brighter 'whiter' feel which will not be to the taste of everyone - particularly the cool white Megaman bulb which lives up to its name.

When one of these bulbs is first switched on, it takes around one second for the bulb to light up, and a further couple of seconds for the bulb to reach full brightness. This feels a little strange at first, but you soon get used to it. While these 11 Watt powered bulbs run cooler than 50W halogens, they are still too hot to touch after just 5-10 minutes (unlike LED spotlights which run very cool) and so the usual rules regarding ventilation around spotlights must be followed.

Note that the Megaman bulbs are 20mm longer than standard GU10 halogen spotlights, which will in many cases cause the light to protrude from light fittings. This can be particularly problematic with flush mounted ceiling spotlights.

The bulbs promise an average lifespan of 15,000 hours - equivalent to 2 years non-stop use, or four hours per day for 10 years. They are also rated to be turned on and off up to 600,000 times - equivalent to 164 times per day for 10 years! - so there is no excuse not to turn off the lights when you leave an empty room.

dimmer switch compatible Megaman 11W GU10 bulb is also available costing a few pounds more but with a shorter average lifetime of 10,000 hours of use. It promises smooth dimming from 10-100% brightness.

Philips Hue, the future of lighting?

Review: Philips Hue Personal Wireless Lighting Starter Pack

Philips's Hue Light Bulb combines energy-efficiency, wide-spectrum LED lighting and remote control capabilities via iOS app into a neat little package, but is it worth the high price of entry?
Hue


The Philips Hue Wireless Light Bulb promises full control of its functions over Wi-Fi, including per-light brightness and color settings, remote operation and geofencing capabilities. In addition, Philips includes a powerful GUI-driven app to custom tune lighting in nearly any environment.

So far, the product has been popular with early adopters, but its high price tag has kept it out of reach for many would-be users. In this in-depth review, we discuss whether the color-changing Hue represents a real value on the dollar, or is merely an expensive one-trick pony.

Design



Hue bulbs are heavy. Carrying three separate LED modules rated at a combined 600 lumens, the base is mostly heat sink. At the bottom is an A19 socket, otherwise known as a regular light bulb socket, attached to an aluminum stem. Up top is a translucent glass dome, under which sits the three-LED array.

Hue


Each tuned LED has the ability to output different colors, which allows Hue to mix shades to more accurately reproduce what Philips claims is a full spectrum of light. In tandem with other bulbs, users can create an almost endless variety of color combinations.

When the bulbs have been operating for any amount of time they become hot to the touch. You can really feel the heat sink working as the upper glass portion remains moderately cool, a good thing for enclosed lamps or those with cloth shades. We wouldn't say Hue is hotter than a conventional incandescent, however. In fact, its metal construction affords a more efficient mode of heat transfer compared to an all-glass bulb.

Inside, Hue boasts a communications module for talking to the ZigBee LightLink wireless standard bridge, which comes with the Hue Starter Pack. This means the bridge and bulbs can be used in conjunction with other LightLink-compatible products, like remote switches, timers and other manufacturers' lights.

Philips estimates Hue will last 15,000 hours while drawing up to 8.5 watts at full blast. By contrast, an equivalent incandescent pulls 40 watts and is usually rated with a 1,000-hour lifespan, while compact fluorescents, or CFLs, are rated at 10,000 hours.

Hue


Philips produces its own LEDs and says the Hue bulb is rigorously tested to ensure low color deviation. The company ensures color consistency to be less than 5 SDCM, or standard deviations of color matching. SDCM is a photometric measurement that defines differences in color. In short, fluctuation in color over Hue's lifetime and between individual bulbs is very low, but may still perceptible to users with acute vision.

Setup



On the hardware side, setup consists of plugging the ZigBee bridge into a power outlet and wireless router, then screwing in the Hue bulbs. From there, almost everything else is done in-app.

Hue


Because the bulbs don't have a physical "on/off" switch, they are powered on by default. When first screwed in, the light is set to a warm tone that mimics light thrown by an incandescent bulb.

Once everything is set up and powered on, the app will direct you to press the sync button on the bridge. Once the bridge is discovered by the iOS device, any activated bulbs should automatically be located and identified in the app. Users can change the name of their lights at this time, or can do so at a later date via the settings menu. By default, the app designates the bulbs "Hue Lamp 1," "Hue Lamp 2," and so on.

Hue


The app also has a feature to add additional bulbs, with the bridge supporting up to 50 lamps for the well-heeled home automation fan.

We didn't encounter any hiccups with Hue's setup procedure, though we did experience the occasional bridge disconnection when first testing the product. Another issue would force us to rediscover the bridge and bulbs whenever the units were accidentally powered down or the ethernet cable was removed. The problem has since been solved, however, allowing hassle-free connectivity even after experiencing a cable or power outage.

In use



The possibilities with remote lighting are already exciting, but add in the option to change colors and Hue starts to look rather enticing. Covering the most important functions first, Hue is a capable everyday lighting system. To be clear, this is not only "mood lighting" or a decorative appliance, but is a viable light made to perform as would any conventional lamp.

Hue


In our main testing environment, also known as my home, we use CFL bulbs in all available sockets. For example, in the living room, we have 55W, 5000K full-spectrum CFLs putting out a considerable amount of light, so we are used to having a bright space.

With the starter kit, Philips provides three bulbs and one bridge, which is just about enough power to comfortably light a medium size room. We think the starter kit can handle anything from a small living area to a bedroom, but anything larger would require extra bulbs.

The app has a number of light presets, including shades of white from warm to extremely cool. Among the preset whites are temperatures designed to go with specific activities. Warmer shades include "Reading" and the almost-red "Relax," while cooler options are named "Concentration" and "Energize."

For our purposes, "Concentration" was used the most, though we did experiment with warmer shades and found their descriptions to be pretty accurate. As an example, "Relax" is actually a relaxing color we would use to wind down at the end of the day.

Philips is big on light research and how it translates to health and wellness. The company has brought a few light therapy product to market, and while Hue is not sold solely on that application alone, the lights do have baked-in features that are said to help modify moods.

Scenes and Light Recipes



If you're not keen on the white shades Philips provides, they can be changed in-app. In fact, Hue can reproduce so many shades of white that the color has its own palette to choose from, extending from an almost golden color to a harsh pale blue.

Since bulbs can be controlled separately, users can tune an environment to suit their tastes, then save the result as a custom setting, or what Philips calls "scenes" and "light recipes."

Hue


Aside from the white light presets, the app comes loaded with over ten Hue settings meant to recreate "scenes," like "Deep Sea," "Greece" and "Ski." Each scene comes with a picture and the app tries to match dominating colors to recreate the image on a bigger scale.

For example, in "Deep Sea," one bulb is set to blue, while the other two are positioned in the same spot on the red jellyfish. Users can also edit the scene by pressing the pencil icon next to the scene's brightness slider.

Hue


In editing mode, both a white shade palette and the selected image are shown. Users can change a bulb's color in real time by dragging an eyedropper icon over the photo until they land on a pleasing shade. Color changes are stepless, making transitions smooth and actually fun to play with.

The app also allows users to import pictures from the Photos app or the Hue online community. We tried recreating various scenes to mixed results. As can be expected, more dynamic and colorful photos play out better than drab snapshots. A good example is a beach scene with a bright blue sky, white sand and maybe some green trees.

Hue can reproduce primary colors effectively, but has a bit of trouble with secondary and tertiary shades. Color matching with pictures is quite good, however, especially when using a bright sunlit photo.

Remote control



One of Hue's main features is remotely controlling lamps. Users are actually forced to use the app as turning lights on and off with a switch will reset them to the default setup color.

Philips offers a number of control options besides the dedicated app. Most notable is a geofencing mode officially introduced in May that turns selected lights on or off when a paired iOS device enters or exits a predefined area, usually their home. When Hue first introduced the feature, it was nearly unusable. Geofences were unreliable and turning on the feature sucked our iPhone's battery dry by constantly updating location data.

An update to the app fixed the battery life issue and tweaked the mode to allow for more customization. The latest version lets users not only geofence, but activate time filters as well. Previously, when geofencing was turned on, lights would go on and off whenever we entered and exited our house, even in the daytime. With time filters, users can opt to turn lights on only after daylight hours.

Hue


Lamps can also be set to an alarm timer, which turns lights on or off at a predetermined time. The setting also allows for more granular control in choosing which days the alarm is active. Finally, a timer can be selected to cycle through scenes at given intervals.

Users are able to save geofencing, alarm and timer settings as scenes, up to a total of 90.

The Hue app also has hooks in If This Then That (IFTTT), which offers a few more remote control possibilities. We tried IFTTT's SMS service and created the recipe "If 'Send Text' Then 'Turn Off Hue.'" It worked so well we use it in conjunction with Siri to turn off house lights hands-free. IFTTT also has recipes to change Hue's color when a new picture is added to Photos, dim the lights and cycle through scenes, among others.

That's another great feature. With wireless data, we can control the lights at home, or at least the ones with Hue installed. Philips makes users sign into a special Web portal to take advantage of the away-from-home functionality, but signing up is worth it as the app is able to relay the current state of each Hue bulb and conduct other system management actions.

Hue


Putting the app-driven automation together during a recent trip, we used the alarm to turn the lights on and off at night at random times to fend off intruders, and would confirm that all lights were off the next day via the Hue Web portal.

The portal also serves as another place from which to control and monitor your Hue bulbs, making them accessible from any internet-connected device.

Hue


Our time with Hue was not all positive, however. We found that the app can only support one bridge and, therefore, one set of lights at a time, which is a problem for users who have a set of bulbs in the office and at home. According to Philips, there isn't much demand for multi-bridge support, so there are no plans to integrate the function anytime soon.

Confusingly, the company's website says that users with two or more starter kits can connect the bridges to their router and control each one with separate apps. As there is no way to easily duplicate apps in iOS, we can only assume the company is suggesting we use different devices for each bridge; hardly an optimal solution.

Conclusion



Hue may not be the light bulb reinvented, but the system is just as bright as standard incandescent and CFL models, more efficient than both and comes with built-in remote control and color changing capabilities.

Hue


When Hue first launched, the software was not developed to the point where it could take full advantage of the hardware. With the latest revision, Philips has shown great progress in not only implementing noteworthy new features like geofencing, but also extending support to third-party developers.

We think this last point is crucial to the success of Hue. By opening up the platform to outside parties, Philips is inviting unique ideas and input to their project. With a large, involved community, Hue's hardware can go further and mature at a much faster pace.

For those looking for a polished remote control light with great app support, tons of automated functions and the option to set "mood lighting," we can recommend Hue as the best product currently on the market. Others who want a simple setup, don't care about light recipes and don't need to remotely control or automate their system would be better suited with another product.

Hue


The Philips Hue Starter Kit sells for $200 on Amazon and comes with three bulbs plus wireless bridge. Individual bulbs can be purchased for $60.

Score: 4 out of 5





Pros:


  • Efficient LED technology
  • Color changing "scenes" and "light recipes" are actually useful
  • Extensive remote control capabilities


Cons:


  • Expensive if you're looking for a simple remote control light
  • Washed-out tertiary colors 
  • Bridge compatibility issues
