I got some news on the lights. I've been try to manufacture my custom QB design for a while and I got the first unit yesterday. This fixture is a full spectrum LED design that has 660nm red boost with Osram Oslon's. I got this unique design optics that have %96 optical efficiency. Unfortunately the Osram driver came wrecked because the shipping personel is terrible here. It is working but it is not perfectly shielded anymore so hands off from it.
This fixture is drawing 300W from the wall and producing an amazing amount of light. Hands down the brightest I've ever came across. I will share PPFD mapping soon to amaze you guys with the results but I already got some temp. values recorded. Driver is around 50, heatsink is around 48 and LED's are around 59 degrees Celsius. These values are recorded in terrible surrounding conditions. 30 degrees Celsius and %50 RH. Tent has 180cm height and the exhaust fan is very small. I think these LED's won't be running hotter than 53-54 degrees Celsius in a 200cm tent with proper exhaust, and 47-48 degrees Celsius in an air conditioned room. I will read same data in these conditions in following weeks as well.
Anyways, I can also build a 150W model simply by cutting it into half and using the 180W driver instead of 380W model. I can dim it because I have the Osram wireless calibration device and I am planning to drive my 150W board at 60W for this small tent. I won't compromise on the heatsink on this model too. Things will change dramatically because this model is even better than my first prototype.
Here is how my new Ferrari looks guys. Cheers
