Sixstrings Led Cob Builds

So I got a question. Have you used both reflectors and glass lenses?

Which do you prefer? Tbh I can't see the need/want for the glass lens at any angle. It cuts down your coverage area so much while barely boosting PAR values

i have not used glass lenses at all.i use a few reflectors,angenlinas on the lower power bars where i have to keep them higher than i would like.it helps push the light down towards those plants instead of spreading.but still i read you lose around 7% using good reflectors and only gain a lil bit in downward light.some guys like having glass over the cobs for spraying,but i have done many foliars under my setups,ya just need to use caution to keep from spraying the lights

how bad would a sheet of plexiglass cut back on light intensity? I can't imagine it'd be all that much?

oh i think it would be bad,like more than 10% maybe even 20%.the expensive glass lenses are made of silicon for a reason and why they cost so much. plexi would prob get damaged by the cobs heat ect. and get hazey pretty fast

Does Cree have any other light to replace 3590

 

[leamon]

Can this be used for diy?

Replace it as in...?

Wow, I had no idea reflectors would compromise output in such a way. Do you remember where you read that? I may be taking some angelinas off soon if this is the case.

Im not sure who did the tests might of been a few different people.maybe Johnson grow lights or northern/hlg or maybe even chilled did some sphere tests with and without.but yeah its pretty much a wash if you use them.taller plants like ours would benefit from reflectors if using lower powered cobs to help put light downwards instead of the good spread ya get from bare cobs.in a tent with short plants i would say always use bare cobs

Well I've gone and done it I just ordered the parts for my DIY COB build
I got 2 ea HLG-320H-C1400B DRIVERS
4 ea BXRC-40E10K0-D-73SE
8 ea BXRC-35G10K0-D-72-SE
12 140mm heat sinks
100' of 18ga thhn wire
multimeter displays
I hope to be building soon

I can honestly tell you that these COB systems are fairly easy to put together as long as you get the + and - correct in your wiring.

I appreciate the thought H4ppy. I have done some electronic work. My background is mostly industrial as an electronics technician for more than 40 years. My biggest concern is the lighting layout. I am going to incorporate my SS400's with the COBs and I'm trying to even out the lighting so as not to have any hot spots. Some of the lights may nee to be closer than 1' apart. May have to do some experimentation.

My lights are up and kickin it! WOW bright light. I only had one brain fart on this build first six COB's were wired wrong only took a minute to correct and now all 12 COB's are lit and putting out some bright light

You're going to love those lights!!!!

 

[Harley09]

Thanks h4ppy I have one more project I want to do RDWC I'm done with soil after this grow I want more control of the grow and hopefully more yield .

Nice lights, your canopy will just explode.

how much was this setup bro?

sweet fuckin setup harley :cool:
