LOL, well.... lookie here
Notice their newest model in their video
New wider spectrum "chip mounted" more natural white LED
(may or may not be the same LED Im playing with, just dunno)
hmmmmm, but no auxillary optics.... and using single chip instead of Tri-Star module.
He talks about increased canopy penetration and the issue with shadows...
Wow... identical observations!
However, notice no heatsinking... so either they are under-driving it or just letting it run excessively hot
Can you say "die young, stay pretty"
(thanks for the heads up Paul)

How much power would a high power single chip LED be using?
Mach, depends on how hard you drive it.... at max it would probably be a little over 3.5 watts
The industry standard is (absolute minimum) one inch of heat sink surface area per watt of power. I am running many times that and using a fan per factory recommendations.
Heat is the number one killer of high power LED's and the effects are cumulative. Every time it gets hot, it becomes weaker.
They are unique in that the light itself is cool, you dont feel radiant heat like you do wth other light sources.... but the LED can get very hot.

Hmmm. OK that is making me think. the vid clip said they were running 4 watts. so about the same, without a heat dispersing unit. OK. all becoming more odd.
I received an email from one of my lamp suppliers, about the Toshiba range of LED lights. They also seem to use passive cooling, even on their 14.5W lamp but they have a large heatsink.
Obviously a much better engineered product then the Orchidweb product.... but the 20 degree models are definitely too narrow for our applicaiton.
I'm very curious, nice looking unit.... what is the price?
(I would avoid Orchidweb's product)
First cape (alba) pic:
(Already showing pretty nice dew production)
The other cape (red) was smaller and is taking longer to recover
