on raising funds for products that don't actually exist yet.
, which is kind of the same thing, only more of a dimly glowing orb than a bulb replacement. They are only $170 thousand towards their goal of $700 thousand with 30 days to go.
More importantly, are these products solving a problem that exists? Never in my life have I sat in my apartment and thought, "I wish the light in here was more purple." Plus, looking for my phone and firing up some app to adjust the lights in the room seems more annoying than just getting up and turning on a light switch. To me these products seem like gimmicky, glorified party lights.
Yet, I will admit that color tuning may be the future of lighting. We are beginning to understand the relationship of light and color and human health, and how gradual changes in color and intensity may aid the wake-sleep cycle.
Also, a wifi-enabled smart-phone gadget that demonstrates the adaptability of LEDs is great for showcasing their capabilities. And it's good news for LED makers that people are eager to get behind these projects, because it means they're willing to shell out >$50 for a tricked-out LED bulb.
Unfortunately, I'm fairly certain the Lifx bulbs will suck. I'd love for these guys to show me their spec. sheet of their final product and prove me wrong, but I'd be willing to bet they will be (a) not very bright, (b) not as energy efficient as it claims (of which they are vague about) and, (c) the quality of light it emits will be disappointing. The bulb doesn't even appear to have an option for regular warm white.
There are a metric shit ton of ways LED makers describe and measure the efficiency and quality light from an LED bulb, including the brightness, ability to render colors (skin tones look like skin tones, reds look red), and color temperature or "warmth" of the light. Researchers and developers have been working for years and spending many millions of dollars to create beautiful, warm white light from an LED bulb that is more energy efficient and as bright as a compact fluorescent and standard incandescent.
It's not an easy problem to solve. In fact, it took
three years for anyone to meet the
Department of Energy's guidelines for an LED-based incandescent replacement bulb. The only company to achieve those goals and win the $10 million prize was a multibillion dollar lighting company,
Philips Lighting USA. The prize was awarded only one year ago and it is rumored that the prize money didn't even cover their development costs. Their award-winning (just white) bulbs hit store shelves
this past April, and still cost around $30 each.
How many PhDs does it take to design a lightbulb? A LOT. (Trust me, don't get any of them started on the mechanisms behind
efficiency droop.) Those of us involved in solid-state lighting research are still trying to understand basic science behind diode-emitters in order to increase
lumens per watt at the chip level. At the consumer product level, reducing production costs remains the biggest challenge. And the Lifx team thought they could get away with development costs of merely $100,000?
Bitch, please.
The final blow is the LED giants at Philips have just released
Hue, which hit the markets in October. Like the Lifx, these bulbs can adjust color and intensity via a wifi-enabled app. They also have the benefit of ACTUALLY EXISTING. You can walk right into an Apple store today and buy it, but it will still cost you
$199.
It will be interesting to follow the success of Lifx and other DIY Kickstarter LED-based projects. There's definitely room for innovation in lighting, but when it comes to consumer products it will be hard to compete with the big boys and their big budget R&D, design, production, and intellectual property lawyers.
