Unlike you....i dont eat enough pies to make my own reflectorsWhat, no reflector? I thought you were the "God of Ali"????? Everyone's just slacking around here, I swear. LOL
IF you are new to LED and want help choosing what to buy, POST HERE!

Yeah, at this point, I think you're right. I'm going to get a 2 or 3 bulb splitter, some cord and put my own thing together with some Cree bulbs. I might choose something else later on down the road, but it seems like the best choice at this point. Thanks for the suggestion.
Read this page, only one about 1/2 way down [Tags/GG] did these measures about 6 months ago. This will give you a good idea of their power and so forth....

Don't use the bulb splitter, terrible umols. With or without CFL's.

Wow! Thanks! I was just looking at the splitters! HA! Nice timing. Yeah the drop in umols was significant enough for me to warrant going with multiple single-bulb fixtures…or maybe trying to wire something together *gasp!* by myself….
Any suggestions for what kind of fixture or fixtures to use?
Thanks

I have some different types of homemade fixtures I made a while ago in my sig... one uses an old hood from a piggyback ballast off a 1000w MH lamp and the others are stripped down Home Depot 3 light bath fixtures....
[I haven't updated in a while, threw a disk out 8 weeks ago or so and just starting to be mobile again.....]
Capn' use to use these and they are dirt cheap...a 4 light cluster, they make a 3 and 2 way too..

Yes! I am trying to fight surgery, but I have injured my back before...sucks, also found a small fracture in the L3, might have been a past injury who knows.....

Looking to purchase A51 LED's
What do you guys suggest for a 2x4x5 tent, utilizing a (5) 5gal Bucket URDWC system.
Mostly, I will flower in it. I was looking at (2) of the RW-150 or should I go (1) XGS-190 and (2) RW-150, or (1)XGS-190 and (2) RW-75, man decisions, decisions. Please guide a fellow here. I've read a lot about A51 lights here at R.I.U but I'm still confused on what combo. Are (3) LED's to much for that grow space. Thanks for the help.

You would only need two lights to cover your 2x4 grow space.
The RW-150 yields a little better than the XGS-190, due to the deeper red spectrum.
Otherwise, they're pretty similar, except for the color of the light emitted.
If you're looking for the bigger yield, go with two RW-150's.
If you're interested in seeing what an all white LED light can do, go with two XGS-190's.
The bigger issue for you is height, as you need 18"-24" between the light, and the canopy.
If you can manage that, you'll be all set.
Good luck.

Thanks, I knew the height was an issue and I know the RW-150's can get a little closer than the XGS-190. I was limited by height where the tent is.
Would (3) of the RW-150 be overkill. I'm going to LST and SCROG it all. And I'm in no hurry.

You're welcome.
Yes, three RW-150's would be overkill.

You might also consider BML Horticulture bars
My led tent is 2 x 4 x 5
2 @ 3ft bars will be here today, which I am adding as supplements to my 2 ufo90s (3500/5000) that were gifted by Jeff at A 51
The bars can be purchased individually, and in various lengths. This can be helpful with budget constraints, as mj does not need massive light during veg.
I think these bars can be much closer to the plants + have passive cooling
Will post pics to my thread as soon they get here

They are talking different stars and possible photosynthesis of extrasolar plant life, but there is some very relevant information in there.

email from A51:
There's a few good options for you.
If you're doing mostly flowering, either the 75 or the 150 is the best option. 3-4 of the 75s, 2 of the 150s, or a 150 and a 75. Personally, I'd go with 3 of the 75s.
Regards,
Jeff
what you guys think?
I'm still leaning towards the (2) 150's for more watts and better coverage I think.

Jeff, aka Eraserhead here on RIU, knows his stuff, and always gives honest advise. Three RW-75's will probably give you the most even coverage, but I would think two RW-150 will give you better results in flower. Either way, your garden will be fully illuminated, so the choice is yours, sir.

Did my previous grow with a CFL but I am planning to switch to a LED for next grow.
I saw a few LED lights with a Red/Blue spectrum dimmable feature. Is it useful ?
Also do these lenses called 3x lens on light better for flowering ?
With a max budget around $100, is more power important or the secondary lenses

Realistically it is the same light, The JoyHydro 180w might have a little more than 87w's at the plug, and then again it might not.
The lenses can help penetration depending on their angle but more than likely are just getting in the way and taking away 10% of the light output thru diffusion.
Then you have the funky spectrums, no doubt that they will veg/flower, but optimally?
At least with CFL you know your spectrum.

To my understanding 90 deg lenses are the most efficient optically (or in other words, least detrimental) Apparently anything else (60,120) can create significant losses. The size shape and material the optics are made from are all factors. Google LED OPTICS EFFICIENCY etc.
