 Topic: Tesla's induction lamps?
Posted: June 08 2009 at 9:53pm |

An electrical engineer was telling me about induction lighting- anyone heard of this? Apparently Tesla patented it over 100 years ago, promising that it could be the end of the electrode-related light bulb. Induction lighting has been available for many years, used in hazardous or maintenance-unfriendly lighting situations. It uses radio waves to make light, and has no filament or electrodes! The bulbs can last up to 100,000 hours and lose 55% of their output in their lifespan. 100,000 hours=a very long time.
I see that Phillips makes a 165w 5000k version, with a CRI of 80 (most MH have a CRI or color rendition index of 60ish, and flourescents have a CRI of 85) with 12000 initial lumens. The drawback is the initial high cost. I think that I heard around $600 will get you a bulb, ballast, and socket. The bulbs are about $180 each, but what if you really never had to replace them??? I saw a brocure with the spectrum, and it seems decent to my eye.
Thoughts?

Have pics and a link? I'm sure you aren't the first to look into them. I haven't researched it myself but I'll look around and see what I can find.

Aquarium induction light commentary It's been considered, but not really tried, it seems. I'll ask the electrical engineer about availability. Interesting, in that the claim has been made that the system's heat output is drastically decreased and lumens per watt are much better when compared with a MH. I see that it has no mercury, no filament, and the long life would be more environmentally sustainable. Everlast FAQ Notice the special order for 6500 kelvin lights.

Okay, double that price... I found out that they cost $1200 for a single bulb setup and don't save any money. Apparently, the bulbs are bigger and the luminares aren't as efficient, reducing the efficiency of the lamp.

Too bad, but I would put money in this technology. I see it coming down in price as more and more manufacturers start to make versions of it. There are claims that it beats LED technology for efficiency.
