Hey all, what's good?

:bigjoint:

I'm looking to test a few DIY LED designs. I'll surely be posting more once things start to take shape, but for now, a few questions...

The nice fit of one HLG-185H-C1400A to four CXB3070 is one base configuration I'm looking at. My concern is the availability of CXB3070 COBs that aren't 80CRI 3000k. Specifically 4000k or 90-CRI 3000k. I'm really looking for a sense of how we can expect more options to open up; I tried to look back and gauge how the CXAs became available to the DIY community and such but I'm sure I'll get my best answer here.

A few of my options have supplemental series... Luxeon 450/660, Cree XP-E2 Photo Red/Far Red 660/730, etc... any input is welcome here, driver pairings included.

Any thoughts on LED autoflower grows in general? I have a 2x5, potentially 2x10 footprint that I may use to test these lights, and I may run with some or all autos. I've seen the journals and results, more interested in opinions and anecdotes I guess.

I've done enough reading to know at least one smart tag to make.. @SupraSPL

Hi and thx alot for all the good infos your spreading. I need some advice here. I would like to replace my 400W Philips Son-T-Pia-Agro with LEDs. CXB´x are kind of a bit pricy so i thought i would go with 4 Vero29s each driven at 2000mA which would be 300W in total of LED power would that match my Son-T in PAR-W ?

I think that 4xVero29@300W would be a slight improvement over 400W SON-T.
SON-T puts out about 125W and there are also significant reflector losses (20% at least).
4xVero29 would produce around 120W and losses would be somewhat smaller.

THX thats what i wanted to hear . I am also currently playing around with the idea of buying alot of vero 8-10s or some Seoul Semiconducters cheap and build a big panel. I cant really decide which way i should go and what would be the most efficient setup (and cheapest ^^).

Keep in mind that drivers make a significant part of the total price. I'd recommend Meanwell drivers. And from MW drivers HLG-185H-C is the most efficient one with complete set of functions and protections and also one of the cheapest. So it would seem wise to focus on this driver if it suits your needs.
Some suggestions:
HLG-185H-C500 + 12xVero13
HLG-185H-C700 + 4xCXB3590
HLG-185H-C1050 + 6xVero18
HLG-185H-C1400 + 4xCXB3070

Just found these LITEON LTPL-M03614ZS50-T0 at 50mA and at 33V they emit 236Lumen/Watt. 49 of them would be 80,85W in total and 19068Lumen, driven at 125mA and 34,4V they emit 170 Lumen/Watt which would result in 210,7W and 35819Lumen. First of all is this a dumb idea to build a panel with such LEDs ? And if not can u recommend a driver that is dimmable like the HLG-series with which i could run these LEDs ?

What type of LEDs, how many, voltage you running them on etc. pp. these kinds of facts and if u dont mind id like to know your average g/w with this fixture.

They are 192X3W . Epistar LED chips , I use it in 12ox120 cm grow tent . Test for one Chinese LED light company .ecosunlite.com

hey guys I want to start growing in my closet. Its 3.5' x 2'. Any suggestions for a DIY setup? How many cobs for that space? Does anybody run these cxb3070s or 3590s at close to their max wattage?
