I just ran across this new light technology coming soon to a tank near you. It sounds very promising if the spectrum can be made like any bulb today. The power of Plasma. Brighter than MH and more Lumens per watt than the best LEDs, and totally dimable with reef keepers.
WOW!

I can’t wait to read Sanjay’s first Road test of one of these.
Wow, that is going to be pricy. Maybe LED is not the future to reef lighting.
OH… MY… GOD… IM BUYING ONE
Ken I looked into theses a couple of months ago when they released them and emailed the manufactor the initial start up on one bulb is little over $1000.00 per bulb, (thats the bulb the mounting puck and the electrical power supply to fire and run the bulb). replacement bulbs are somewhere between $400-$600 each. They have a very large lumen output but the max color temp when I checked was 6500k . There maybe more color options later down the road but as of 2 months ago that was the highest. These bulbs were designed for street light operation.wow those are intense. could be good down the line once they explore more applications. only time will tell.

I agree, once there out there hopefully the price will come down, cause there lighting output is amasing but untill then I'm sticking with my MH.Yup, Im sure there will be limited kelvin options at first. their money play is for street/high bay warehouse lighting. reef lighting will follow as a niche market. but im pretty sure with the right doping of phospors they can make a fine 20K kelvin lamp, someday. the day they send one to Sanjay for reef testing will mark the beginning of reef applications. but that’s pretty good. 140 lumens per watt. much better than 70-80 for LEDs.
More info, apparently there are DIY kits out there already for around $600

i would be concerned with heat considering the sun is composed of plasma…

Glass is also a plasma, look at any early 1800’s windows, all the glass has “sagged” making the tops thinner than the bottoms. your blood is a plasma… ect ect.
from what i read they have very low heat output.
While i was reading that i noticed they were disappointed by the 1100 PAR value at full power, but consider they measured that at roughly a 5000 kelvin rating i hold hopes for when they can tune the kelvin to 20,000 kelvin @ full LUX, as the optimal PAR is around 450nm with a high LUX the PAR should be outstanding. (also considering i have 6 bulbs to get a 1700 PAR rating)
They state they can get 20,000 kelvin but its like at 30% power
Well, as always, reefing parameters are a far secondary consideration in new light developments. They are first looking for general area lighting. the spectrums of our particular niche needs will follow after experimenting with various doping elelments for the bulb. that would be a refinement. 20,000K lighting for reef tanks is not their primary market. but it can, and will come.

plasma is 5th state of matter, that sagging in glass is denoting an “amorphous” compound and has nothing to do with plasma to my knowledge. glass is simply a compound containing mainly silica. the plasma your referring to in blood is a suspension fluid for leukocytes and erythrocytes…many different definitions for the term, however the “plasma” being used for lights is an ionized gas, which can produce significant heat.
looks like someone’s already about to sell one for aquariums, still at 100% its 5300 kelvin, but you can dim it down.
Six years on the bulb rather than 9-12 months for halides?!?
Its got a nice fat curve of blue in its spectrum. thats good for reefs.
