I dunno, that hotspot is pretty brutal. And robincnn said they were narrow and very fiddly, since they are lenses. Had to be positioned just right.
 
oh wow, that ledil stella lens would be pretty sweet for my setup since I have a cob every square foot. Would i be able to fit one onto the cutter heatsink?
 
If we are talking about the LEDIL Stella : FN14074 . or FN15186 it has a diameter of 90mm. this heatsink is 107mm at the flat sides 111mm OD. that is all the information I can provide, since I have never put my hands on STELLA!!!
 
And by the way, there are 60 degree Angelina reflectors, which would be a hell of a lot easier than adapting a lens if somebody wanted a narrower spread. But I think 90 is standard for a reason.

And @BobCajun what's interesting is that everything 60 degrees and below in the Angelina line is a metalized reflector, and the wider angles are translucent. Makes sense, now that I see it.
 
hi guys

i went out and bought myself a light meter today. not PAR, only lux but still. so i got my lights like 40 inches from the canopy and the meter reads 25000 lux. rigged up the old light (no brand chinese burple) and took a reading of it at the same distance. it read 9000 lux, and that was the closest i dared to have that piece of shit to my plants since they were exhibiting various signs of burn when it was closer.
i reckon im at like 40% on the potentiometer now, so question is whether or not i dare turn it up a bit more. using the same meter i took a reading outside. sunny day clear skies the meter read 25000 lux in the shade. what do you think fellas?

all good, db

Your flowering plants can take 50,000 LUX of warm cob photons easy...that's about 750 ppfd. I'm on my 3rd run of doing just that and the girls love it! What kind of reading are you getting say 12" below your cobs?
