Okay, so I have a veg light project under consideration and it seems to me that citizen is competitive at a way lower capital cost. I noticed the 1212 chart that it is measured@1050mA. How does driving it softer (350/500mA) affect the numbers?
I'm thinking the 1212 is a cost effective way to get as even lighting as possible. If my thinking is off I'd love to be told.
I'm undecided on color temps yet, 6500k or 5000k. I've seen both work, but do you have any impression from your business which is the most popular?
I just have to learn how to calculate heatsinks and I'm going to order. Is your end of October delivery a large one on the 5000k? If not I'd like to pre order. Yeah, and is the bjb holder solder free? It's a sexy little thing lol.

im testing the active light engine with a 3618 chip
hlg320h-c2800b + single clu058-3618 6500k 80cri
wide open test:
cold startup
V 113.3
A 2.88
W 326
PPFD at 12" = 3640 umol
steady state after 5 min
V 113.3
A 2.88
W 326
PPFD at 12" = 3417 umol
temp droop is 6.2% of the cold start up lumen value
based on citi simulator thats a case temp of 59C and looks like
do we have a $200 315CMH killer here or what? this is veg light but obviously can be anything.
-----------------------------------------------
also new toy bump. spits out this
but also produces this which should be useful

Well post it up so we can see. My T5 is my favorite light so far that I have used as an "overall" light and it rocks the house in Veg. This would be a killer replacement so please let us know what area's can be covered and PAR measurements etc.......

i love the coverage but hate the <90 lm/W. hoping i can duplicate the dense lush results with this hung high instead.
i also have some 5700k and 6500k cutter strips coming. those vs this beast will be a good test of distributed low light vs distant intense light on stretch, etc

That's an unbelievable par for 12" from a Single cob.

The spectrum also comes into play there.........not just distance from canopy
