The app for Philips' smartphone-controlled color-changing LED light bulb, Hue
, has been updated with a number of well-thought out additions which multiply the possibilities for automating its behavior in all sorts of interesting and useful ways.
Just over a week ago we reported that Philips' 22 W LED light bulb
, designed as a like-for-like replacement of a 100-W incandescent light bulb, was the first LED bulb of its type to receive the stamp of approval from Energy Star. But looking at the Energy Star requirements reported by Philips in its press release, it seemed a little strange that Philips' product is the only one to have been certified – given that products long on the market appear, at face value, to meet those requirements. Since then, Gizmag has spoken to LED light bulb makers Switch Lighting
and other industry players to find out why they're apparently playing catch-up.
Philips has announced that its 22-watt LED lightbulb is the first 100-watt tungsten equivalent bulb to have been awarded Energy Star certification. Often referred to as the A21, which is actually just one of several standard forms for light bulbs that this bulb happens to conform to, Philips' 22-W bulb puts out "nearly" 1,800 lumens for an efficacy of about 82 lumens/watt (lm/W). It's a fine spec, but not too dissimilar to the competition, which raises the question of why Philips' product has been singled out.
Until recently LED light bulb manufacturers have struggled to find a solution in the 75 to 100-watt range
which successfully replaces the soon-to-be redundant, energy crunching 100 W incandescent bulb in terms of size and brightness. Three friends from the University of Toronto are the latest to offer a feasible product to match the classic 100 W bulb without compromising on electricity consumption with their proposed NanoLight LED light bulbs.
Combining the power of smartphones, LED light bulbs, wireless and remote control technology has inspired designers to come up with smart solutions such as LIFX
, Philips’ hue light bulbs
. The Lumen Smart Bulb project, currently raising funds via indiegogo, aims to add one more option to the wireless-enabled LED market, while betting on home entertainment and well-being to score extra points.
Purveyors of fine home automation technology INSTEON claim to be first to market with a "networked remote control dimmable LED light bulb". Compatible with any INSTEON remote control, the bulb can also be paired with INSTEON's free iOS and Android app so that it can be turned on, off, or dimmed, using most contemporary smartphones.
Following Gizmag's coverage of GE Lighting's 27 W Energy Smart
and Switch Lighting's 100 W-replacement
LED light bulbs, Osram Sylvania has been in touch to tell us about its 100 W-replacement LED light bulb, joining its Sylvania Ultra series: a 20 W, 1600 lumen light bulb with a warm, "incandescenty" color appearance of 2700 K. With Philips also to release a 100-W equivalent this means the big three manufacturers of light sources are joining Switch Lighting in offering high-output LED light bulbs for the home, but all things considered, Osram Sylvania's may prove the pick of the bunch.
GE Lighting has announced that it is getting in on the 100 W-equivalent LED replacement act. The 27 W Energy Smart LED bulb joins its range of incandescent bulb replacements that already includes 40 W and 60 W equivalents. And like an incandescent bulb, GE claims its LED bulb emits light evenly in all directions. But how does the 100 W equivalent stack up performance-wise?
Combining lighting with audio
by using a light socket to power a wireless speaker is a two-in-one approach that appears to be gaining traction and this latest example - the Sound of Light speaker - grabbed our attention on both the functionality and aesthetic fronts. The Sound of Light system uses a Texas Instruments 2.4 GHz Purepath Digital Signal Transmitter to set up a wireless link between an audio device such as an MP3 player, smartphone or tablet and up to four speakers within a 300 ft range.
LED light bulbs are becoming increasingly popular with designers and consumers of green technology, as they use less electricity, last longer, and emit more light on a pound-for-pound basis than traditional incandescent bulbs. However, while it may be tempting to look at them as having solved the problem of environmentally-unfriendly lighting, researchers from the University of California would advise against such thinking.
