Today Lighting Science Group unveiled a new 60-watt replacement LED bulb that “meets or exceeds all of the criteria for the L Prize,” according to CTO Fred Maxik. If you’re not familiar with the competition, in order to win, the lamp must run better than 90 watts per lumen, produce more than 900 lumens, use less than 10 watts, last more than 25,000 hours, have more than a 90 color rendering index, and have a color between 2700-3000 K.
Velux makes some great products for drawing natural light indoors. The company recently introduced a new, low-profile, flat-glass Sun Tunnel skylight at IBS 2011, and it will be available later this year. Already in use in Europe, the new skylight trades the bulbous, dome-style, roof model for a sleek, more modern, less noticeable look.
Some folks are stockpiling light bulbs in anticipation of the future phase-out of standard incandescents, according to USA Today. It seems hoarders are doing it for one or two reasons: cost and/or lighting concerns. But these shouldn’t be concerns. With a little bit of math (initial cost + operating cost) and an understanding of basic lighting terms (lumen, watt, color accuracy, color temperature), I think the switch is a no-brainer. So here’s a five-step program for the hoarder:
Cree, Inc., manufacturer of the popular LR6 LED downlight, just announced a new light bulb. The company unveiled “the brightest, most-efficient, LED-based A-lamp that can meet Energy Star performance requirements for a 60-watt standard LED replacement bulb.” Cree attributes the bulb’s performance to TrueWhite technology and a patented remote-phosphor technology.
I’m going to be honest, I hate my CFLs. After blowing all sorts of cash on these things, I’ve yet to find one that performs the way I’d like it to. Plus, since lighting accounts for some 11% of residential energy use on average, it’s an area that deserves attention. In doing so, I’ve been playing with various options and think LEDs may just be the ticket.
Keep an eye out for the next acronym in energy-efficient lighting: ESL, or Electron Stimulated Luminescence. ESLs use “accelerated electrons to stimulate phosphor to create light, making the surface of the bulb ‘glow,’” according to Vu1 Corporation, a maker of ESLs. The technology is being touted for producing light that’s similar to an incandescent bulb but about 70% more energy-efficient.
