ok. Back to the more serious discussion... the V4 ORPHEK is the best single lighting system i have tried hands downs. Just trying to help...
I can grow coral with a Coleman lantern in a 5 gallon bucket.
I betcha many do not know what a coleman lantern is?

i am dumping LED and going to quartz.
It was the sound of the gas lantern plus the light that really made it such a cool device for camping. I wonder what that spectrum looks like?
Incandescent gas mantle lanterns work by using kerosene as a fuel to light a mantle, a bag of cloth covered in metallic salts. ... Many mantles in retail lanterns still contain Thorium, with 50 million mantles sold in 2000 containing the radioactive element
The danger from using these mantles around a campfire one or twice a year is not substantial, with exposure of roughly 0.005 millirems coming through a couple of nights spent by Thorium gas lantern light. Under extreme exposure conditions "” 4800 hours during a year from simultaneous use of four different Thorium mantle lanterns "” an individual is exposed to roughly 200 millirems. This is not a large amount, as 200 millirems is roughly the same amount exposure you would get from receiving a CT scan of your head.
I have been playing with LEDs for two years. L
Im adding blue leds for pop/dusk and dawn which is all I miss from that system.
interesting.
I am not sure plasma is going anywhere, I thought maybe it would.
At Lightfair this year I would have thought I would see several fixtures and there were none.
Maybe that will change.
I don't think it will go anywhere, they weigh a tonne ! They are expensive and colour control is limited, limited install options due to their size. Only thing going for them is that awesome smooth spectrum and bulb life. They entered the market too late, they lined up with Led, bad timing, 10 years earlier and they would have had a chance until led.
