Lighting Interesting LED design

[Torched]

I just saw this LED light and it's design really caught my eye. It's called the HILED by solis tek.

It looks like they are making it aircooled so you can hook it up to your ducting for traditional heat removal and no internal fan.
The other interesting thing is they are trying to replicate a HPS spectrum rather than picking certain red and blue wavelengths.

Does any one know if those COB diodes are as good as the individual diodes?

Interesting looking light and I'm wondering if it's just for flower if it's based on HPS?

looks cool every time i think on getting a led i find 100 cool lights,

I emailed for info and although they didn't have a lot they said the LED's were modular so you could replace the 2000K with a 6000K COB module or any other color range you want. Even 10000k which could be good for growing corals. The website says all stages including flowering.

As designs go it seemed the most unique I've seen with an emphasis on the tent grower.

Here is a grow log for a guy using 4 cobs on a home made system: COB Grow I think he's just vegging with them and then firing up his awesome AT600

p.s. the pics are halfway down the page on the link and there are endless technical details about cobs etc.

mate the next few years will be really interesting for us LED buffs especially with companies designing and making there own units in house.

I myself am going to give COB a bit of time to prove itself and level out before I pay for one, but honestly my Vipar WITHOUT and air cooled hood is fine in the tent. The hardest part is finding a way to remove the heat from the surrounding room which you would still have to do with HPS etc. I don't see how this will benefit an LED that much when it comes down to it unless it is VERY high wattage and puts out a LOT of heat. I could see this being helpful if you had a large room with multiple LED units and no real heat exhaust setup per se but for a tent, way overkill.

Ok I've done a bit more research on COB and I feel a bit dumb not realising that I've got a house full of cob lights already. Yup, it's my standard GU10 led bulbs that I'm talking about

The GU10 domestic bulbs are obviously made in a factory and would be very difficult to make at home due to the the very small parts used. Scale the chip on board bulbs up from 3w to 50w/100w Cree bulbs and then you are talking about a housing for the COB unit something around the size of a baked bean can. The rest of the components are obviously upsized and more manageable so it is very possible to build your own.

For me I would need one 100w unit for my tent to become like a summers day and since I build computers it's not a great deal of technical effort to make it myself so I'm going to watch how well they do in a couple of grows I'm following and make that my Autumn project if I can get all the parts by then and it's worth doing. Big bonus that it's modular so you can change the bulb over to different bandwidths throughout your grow.

From what I've seen on the interwebz, grow light COBs are already producing plenty of useable light, the equivalent of a summer's day so pretty close to outdoor µmols/brightness.

The air cooled unit the OP posted about is a pretty fair attempt by an HPS company to get into the LED market, imho the air cooled hood as a base for the 5 lamps is overkill but if they have the stock sat in their factory then it would make sense to use what you have and also be the first to market with a version that can be hooked straight in to an hps setup, good marketing strategy to tempt hps users too!

Anyway, Gadgetguy has the right idea, watch what's happening out there with LED technology and wait while it's tested by others or be daring and try it out your self

Hi guys I've just brought a 675w cob led grow light from china, I was going to go for the Helios Pro 9 from QuantumLED but after abit of research and digging I found this http://www.aliexpress.com/item/Free...e-cup-spectrum-grow-light-for/1887770559.html which is basically an unbranded Helios Pro 9 at half the cost, Now I've not grown with the light yet so I can't comment on how well it performs but what I can say is the cob seems to mix the light spectrum really well and the light refraction with those reflector cups is awesome I think the cob could well be the future of LEDs if that technology is here today well I suppose I will know soon enough.....

COB are the future and they are great.
Still, there is a HUGE difference between the chinese average crap and first class COB manufacturer products.
