re: LED GROW TEST. 126W hydro grow led VS. 180W
Nice job irishboy, and great journal! We're in the homestretch, not too long now!
And for those who contacted the above companies and posted their feedback here, thank you for your efforts. This is a great community here!
So where do you think the drop shippers on here operating these so called "companies" get their lights from?
The reality is 95% of LED grow lights on the market are made in the Shenzhen district in China.
The only difference between you placing the order and a drop shipper doing it for you is the final price you will pay.
Infact, bsled is probably the exact factory where the HGL lights come from,they are the only company ive seen with the identical mould,
they also offer OEM (your own spectrums)...(might call mine a Detonator...)
I take it you got my PM too, eh tbrad?
Maybe you should call yours the
Instigator, or maybe the
Perpetrator--! (jk)
Cat's out of the bag now for some folks, I suppose...good!
I've been looking at those too over the past few months. The better companies (like the two you listed) have sales reps fluent in different languages, a large % of their business comes from overseas; for some of the others you have to deal with broken/poorly written English on their websites or know Mandarin pretty well to get much traction. Many will do them to spec, and don't necessarily list all the options on their site, as you mentioned.
Bridgelux, Lumileds, most of the US-based LEDs are available in bins for made-to-order jobs, many lenses (30/60/90/120) are pretty common, just tell them what you want and they'll give you a quote. Then the only question is whether you're ordering just one, or 100/month. Drop shipping can be fairly lucrative if you know what you're doing...
Nothing wrong with the better Chinese manufacturers. Sure, you get what you pay for, but that doesn't mean
good also has to be
expensive. If you can save a few hundred $$$ by not having them assembled by US-based Union Rep laborers, then why not?
More money for groceries and utility bills...or even new strains...
I contacted BSLED and about the RS-43 and was quoted $700-$850 depending on the ratio of lights I chose...
BSLED builds lights to your specs so I can get whatever works best...
I would appreciate an input from you guys before I drop the cash, but it seems $800ish for a 600w LED is a killer deal.
Hi Cap'n CaveMan! Welcome to the forums. If you can save some money,
go for it! I have a fair idea what spectrums I'd probably use, but every garden is different...I don't think there is such a thing as an 'exact' ratio in any case. Even using 'Chinese' products,
Mr. X on that Spanish forum got ~
2.1+ g/w a few weeks back using 200W LEDs. I still think the 2-1 wattage equivalency rule applies pretty well from what I've seen (1W LED =~ 2W HPS,
when used correctly.)
I've looked at those boards you mentioned, and prefer that (Bai Sheng's) profile over the offset Chevys for larger lights (though the Chevys appear built like a tank), though both have their uses. Personally I think 600W of LED is
way overkill in that kind of space and inefficient, better to spread them out a bit than try cramming all those lights so close together, as I reflected on a few weeks back in the
TL's LED Swipe File I put together as a scratch pad for ideas (couple paragraphs to either side of the 'Current LED Grow Light Designs' header). Think a T5-HO PL-L profile but more evenly distributed and you've got the right idea, IMO.
If I went for a custom unit, I'd want something to fit over a
2x4 Ebb and Flow system for a nice tight SOG or ScroG, and in lieu of a larger, more expensive custom light board; the
BS-43 using 90 degree lenses at 7-8" over the canopy would fit quite nicely. A checkerboard pattern (~288W) using every other PCB spot would be plenty in that case (the board is 12 x 48), run cooler, and still give you fairly even lighting. Though you'll still have some diminishing returns with that setup over a two row plant system from the light, but much less than using all 576 spaces in close proximity. The inverse square law still applies - better to spread that light out a bit!
And, part of me thinks it'd be even better to run four rows (at, say, the 1, 4, 9, and 12 positions) of mostly blue/red (various) with a smattering of IR and white, etc. interspersed throughout the board, and get results almost as good, using less wattage. Call it
210W minimum (196W of mostly
blue/far-blue and
red/far-red rows with 10
white and 8
IR),
up to ~250W if you want to fill the board out a bit. Put a little mylar around the edges of your garden, and you're golden.
(With a 400W HPS over 2x4 (round lighting pattern), you still have areas not well covered (unless you have a light mover), there's a 2ft distance from the point source light at the ends, and your distribution suffers. A 600W makes up for some of that (and improves your yields), but you still have the pattern problem. Give me several hundred LED light sources evenly distributed, and that becomes much less of an issue - and you can use fewer watts to do so.)
And you should be able to get two of those style units for not much more $$ than one 600W LED panel, giving you much greater coverage in a larger garden. Biggest costs are for the LEDs/drivers.
(And the smaller you get with a board, the higher your $$/watt cost, since some of the components (inverter, casing, power supply, cords, etc.) are obviously fixed vs. being variable costs, which is why making small wattage strip lights for these (as supplemental lighting, for example) becomes cost prohibitive for most distributors. You can make them, but people won't necessarily want to pay for 'em. Less so if you go direct, (and can get qty discounts). Might still be better to use a couple of T5's for side lighting, though...for now.)
But if you just want to blast a smaller area with that much light and have the $$, that's as good an option as any. Depends on how you'll be using these. Anyway, my $0.01...
If you do, let us know - and put up a journal over here so we can track your progress! Good luck!
