Blondes LED COBS?

Figured there would be a lot of multichip lights converted to cobs...bound to happen

Everyones following the riu recipe...:P. I guess they aren't afraid of the high voltage drivers? Someone could get a zinger without the right protections in place. Just my assumption though..

I would guess they are contacting the light sellers and arranging something...that lights probably been around awhile as a cheap multichip setup

pretty dam expensive either way you look at it curious says Cree USA COB could that be a marketing scam ?? or the actual COB light is made in usa or the fixture and parts from indonesia , china etc
Also what would that 825 watt go up against ??? for hid like 2000 watts ??? or two 600's ??

if people thought of LED like people thought of monsanto lol i think lots of eyes would open up
in 1968 the Monsanto company first organized mass produced visible LEDs using gallium arsenide phosphate. Quickly propelled into mass adoption in handheld devices such as calculators, wristwatches, and digital displays of all types but until around 1995, were not considered bright enough for any replacement of traditional lighting.
as for next generation probably be MCOB

Multi Cups/Chip on Board) MCOB LED technology
The Next Generation of LED, is without doubt; Multi or integrated Chip known as MCOB (Multi Chip On Board) or MCCOB (multiple chips and cups on board)

This new LED lighting technology comprises of many small-chips integrated into one large single chip.

These are used widely now in floodlights and High bay lights. They are cheaper to assemble than multiple single chips and so make products like high bay and floodlight, much more affordable than multiple one worth reading what chips. The more well-known companies working on this technology are Bridgelux (USA) and Edison and Epistar (Taiwan). As with all LED products however, the drivers and thermal management are the key to LED product longevity.

CREE and a few others make integrated chips, but are currently prohibitively expensive. MCOB is also found in LED bulbs and LED tubes, however compared to SMD surface mounted diode technology, MCOB technology is still in its infancy. Watch for this exciting new technology new ultra efficient high output LED lighting.

Hard to tell. Obviously the parts are made over seas, but where it was assembled not sure though it looks like it ships out of Canada. In any case it does seem to use genuine Meanwell HLG drivers and likely uses real Cree COBs. Makes me wonder if there's about to be a new COB brand on the market. They seem to have a brand name picked out.

Anyway, to answer your question, it puts out about 7% more light than a 1000W HPS though not nearly as much as 2. It also generates less heat and uses less electricity than a 1000w HPS bulb. At 200w less for more light, the extra expense will be more than recouped over the life of the unit.

The chips are being under driven, so they should last well beyond the nominal life expectancy of 5 years.

LED technology is still evolving, but all the other parts of the lamp won't see any real price drops over the next year. The real change will be when a large company starts buying in bulk. That would lower prices short term more than tech upgrades. Efficiency may go up a bit over the next year or two but not enough to realistically outdate a lamp made this year. Besides, if that lamp will be outdated next summer, HPS is already outdated and will be even more outdated next summer.

Anyway, if you're thinking about testing LED at some point that's the kind of LED you want hanging above your plants. Cree or Bridgelux COBs 40% or more efficient w those aluminum cased drivers (not Edison or Epistar). Not suggesting you buy that particular lamp, but there is 1 company already using that tech (Opticgrowlights) and another one about to (Area 51).

yeah but until LED blows HPS out of the water its not going to change much for commercial growers you know the ones harvesting 100 kilo a month :)
for instance that one on ebay is 1600 bucks plus for that price a person can buy 3 1215 watt nano lux and pull 2.5 - 3 pounds per light consistently so any wheres from 7.5 pound to 9 pounds i can guarntee you that light your lucky to pull 2 pounds
Now everyone is going to scream efficiency but at the end of the day is still blew away from that 1600 dollar unit it cost to load up on HID for the same price
owe but then there will be its produces a better product lol right
Again i grew organic if that's the case but strain wouldn't matter for quality right
all it is is really is what ever you are able to grow some people grow ware house style some people grow in a closet just grow and be happy you didn't get caught

No reason to disagree with that. Just keep in mind, total cost over time is now in favor of LED. That hasn't been the case in the past with blue/red single diode lamps. It's a big up front investment but eventually someone growing commercial will jump in and others will follow. I agree it will be at least a few years before it becomes a trend.

I'm not really concerned with whatever light a person chooses to use, though you obviously have some interest since you keep posting in LED threads :)

Anyone ever heard of this?

Other question is - where do we get these empty cases?

Does this lighting fixture remind anyone else of GreenGene's proposed fixture?? I guess it doesn't have the slick chamfered corners,,,

COBS, MCOBS, HPS, HID, candles, potato bulbs - I like options; one can never have enough options and there will always be a need for more options.

We live in a glorious day, boys, where technology fuels our pleasures and lights guide our future.

Damn thats going to be a lot of light crammed into a tight space, and with 4 meanwell drivers crammed in there as well, u can't imagine cooling is very good.

This fixture looks to be legit and is consistent with the setup people are using around here (hlg185-1400 per 4 cxb3070) x4. But as far as I can tell, the unit is 18"x18". That is a lot of juice without the benefit of the nice even spread we get from our diy units. The manuf website as well as the eBay listing is basically saying " hang this baby 3 feet above your plants, or it will burn the shit out of them, esp the poor plant in the center of the tray.

I would consider buying this light if the fixture was 30" x 30" or even 36" x 36". Why don't these manufacturers get it, a lot of us want a large footprint fixture to hang over each 4'x4' area. Obviously , shipping big fixtures is troublesome.

My 9 cxa3070 @ 1400mA started bleaching my plants at 12-18" above the canopy, How high do you guys hang your diy cob fixtures above the plants (late veg/early flowering)?

I cant wait until CoBs are outdated. Nobody will want them and I wont have to pay so much up front to beat the pants off HID.

Music to my ears, Darth!

Wow, nogod_ spoke here. I am honored :)

Seriously, this site has pioneered a lot of this knowledge and my hat is off to all of you!
