Nothing like seeing electrical outlets right next to a "big body" of water to get me feeling all warm/fuzzy inside

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.

I agree plastic quality of lens, its proper mounting on led and lens size play an important role in efficiency. Can be anywhere between 80-90% efficient. Check out the secondary lens pic at the end of the page. It seems the 10-20% light loss is small compared to the gains.

At least with CFL you know your spectrum.

Thanks, I think I will do this 87watt UFO with lens and compliment it with 40-80 watts CFL. This should cover about 2 square feet

@PSUAGRO. - You should have seen how close the center of the pie tin was to the socket plug tynes! It was not optimal to say the least. Sometimes my desire to DIY is greater than my common sense!

are you selling us this light or asking for advice...

Question for you fine folks before I place my order. I'm considering nine, vero 18's driven at 1400mA for a 2.7'x2.7' space. Four, 2700K, 90CRI and five 4000K, 90 CRI emitters. According to my very rough estimations. That should be about a (unintentionally) 420watt fixture including fans and output about 32,000 lm, assuming a 50*c Tj temp.

What do you guy's think? Over kill or under kill? Shooting for something that would be comparable in price, power draw, and output to those new Philips 315watt CMH.

I know LED strips aren't really as effective as normal LEDS, but I've made a small panel off a 5050 smd led strip, 14,4 W/m, and I'm planning to do a small PC grow because I've seen couple LED strip grows here. So, my problem is, it's a RGB diode strip and I'm currently running only blue+red,leaving green color off. My logic behind it is that the red and blue are supposed to be more intense if the green is off, and I'd like to know if I'm right about it, also, will adding the green color in (which will altogether make the strip shine white in color) add anything to grow or should i just leave it off? Thanks in advance.

okay i dont want to spend time trying to find this answer....

What is the cheapest yet still somewhat effective LED light someone could buy for a closet grow of 4 plants?. and I WILL NOT use any multi band purple light nonsense...strictly white..2700K/5700K or what ever you guys would think is the best white aspect ratio or mix of colour temps.

Cree LED light bulbs, they're available at Home Depot.

Had to move from med mj state to non med state for family reasons. I need a stealth grow room in my new place to replace the 600W hps I had. I was looking into LEDs because there is less equiptment, heat signature and worries. I want to grow 1-2 plants in a 3X4X 7 area in FFOF to keep it simple. I am looking at 700W to 900W Red/blue/white with a range of 400-700mn with a infrared light and lens around 90 degrees. Am I looking at the right lights?

I hope to have a 600 by next weekend

^^^Your BML ranting is growing tiresome. Stop shilling and start growing, then you can SHOW us how great they are instead of assuming it.

I'm a first time grower...any suggests?

Find growers whose LED setup you like or think that's right for your situation and go for that. No shortcuts. No cutting corners. That's my .02.

Extra emphasis on not cutting corners. It always ends up costing me in the long run when I do.

Funny. Haven't seen you say the same about ALL the A51 comments .

Anyway, look at the title of this thread

Your comment is out of bounds here

I AM using 2 BML light bars + my 2 white ufos

However...

Due to 2 males, I moved the probable female from the led to join the other probable female under the hot5, which will be replaced as soon as the Spydr 600 arrives. Maybe by next Saturday

So IF you really care to watch, the BML + ufos are covering 3 clones taken today + the one plant that I was forced to FIM + a heavily trimmed male. So not a lot to see in the led tent just now

Yeah Pet but A51s are proven to grow and it's not just Ehead saying how great they are. I mean GG can be a shill but you can't deny Apache is solid. Now I'll be quiet and watch your grow with great interest. Good Luck PF

I have to agree with FranJan, Pet, you are really over doing it.
Every post of yours I see, no matter which thread it's in, you mention/recommend BML.
You're post are becoming spam without you even realizing it.
Besides, I don't know how you can recommend a light that you haven't even done a full grow with, yet.
What if the light is shit?

OK, but when people in this thread keep asking what to buy, I offer it as a suggestion

AT is solid, but expensive

Not that $1000 for the Spydr is cheap, but they say it covers 4 x 4

You would need 2 A 51s for that

Everything I've seen from BML is honest. Man knows his stuff as it relates to how to build a proper led panel for horticulture

Perhaps if you guys checked them out you would see why I am enthusiastic

Each of my 3ft bars have 45 @ 3w Oslons. Not exactly shabby

Yeah I also agree with this..........You can't come in this thread and recommend something that is UNPROVEN unless you state so.............like my illumitex neosol "obsession" , still wish someone would do a grow with it, I don't have the space too.

What's up with the solar genesis units coming out on july 1st? look's promising

I'm not sure how they are able to sell it for less than gavita is selling their plasma, AND they have 4 kessils led's attached... anyone want to explain? are they not the same plasma chip?

I can see the future of lighting i this industry heading towards controllable and dimmable led's supported by plasma.
