anyone see this yet?

price is high, but would be good for supplement or for some small veg plants, or who knows, get inventive, they are small it looks like so you can hang them wherever or do whatever... 35 watt I believe. not sure one what leds used or anything..

please share thoughts, opinions, anything on this light

Interesting light to examine. It claims to use 21 LED chips with input power of 34 watts. If we assume a 90% efficient driver and a 3 watt fan it might dissipate 28 watts. That is about 1.3 watts per LED, similar to many on the market.

One concern is that it packs all this light into a small footprint, eliminating one of LED advantages which is to spread light evenly. Another concern is the lack of white LEDs. Some strains need white for the trichs to mature on time. White is commonly added and shown improved results. Finally I wonder about the efficiency of the LEDs used, they make no mention of it so I would assume the worst, especially for the 660s.

At $250 we would be paying $9 per dissipation watt which is almost double the typical cost.

it sounds intriguing, but the cost and only 1 spectrum as well as such low wattage being used kind of makes me wary, seems like a mixed spectrum kessil would be a better option right?

i cant belive to get the chips cooled well on such a small space, and of course 250$ for 30 watt support lamp?? but the lamp looks nice
a very funny quote from the kessil hp, they invested 30 million dollar and five years to develope the led..... for sure !!!!mwahahahahah

kessil keeps pumping out product

they have a few multiband lamps, some with wide angle instead of the narrower beam

now they have their 90watt 350 model out, the "spectral halo", still very curious, if there's money to toss one day maybe i'll bite

I have a kessil grow going on, not concluded as I want to run some more tests to try and maximize the light potential

you can find it in the autoflower section, as I'm to tired to find it right now..

No way in hell I would buy one of those. 30W in that small of a space would be too much heat generated even with a fan. The junction temp will greatly affect the output and efficiency of the LEDs. The spectrum looks to be lacking white also as Supra mentioned. Cannabis grows better with a full spectrum, why these LED manufacturers don't understand that is beyond me. Even if used as an added spectrum light it is pretty weak when considering price. Its just over priced any way you look at it. I'd like to see some plants flowered only with this light.

$250 for a measly 30 Watts? Get real.

^ I am flowering with it if you looked at my post above yours


I sent an email to kessil about white led's.. they say there testing has proved no difference to add white LED.. that's what they said to me


yes, $250 might be alot, but if you know, there are some micro growers here, that grow in PC's, which I think this would be suited for, maybe clones ( never did it yet ) or side lighting.. I do believe they have a ways to go with this but for experimenters it is a good tool I believe, as no one has done a micro LED like this before

I was wondering the same thing about Kessil. But a more focused light distribution should have deeper penetration through foliage.

The area coverage is demonstrated here as being a circle of .52 meter diameter (about 18 inches) from a height clearance of 40 cm. (about 16 inches).

I currently use a 150w HPS to cover a smaller size space (15" x 15" = 1.5 sq. ft.)

Also the beam angle is it really 33 degrees or is it 2 x 33 = 66?

I'm close to pulling the trigger on the 350 magenta for supplemental lighting in my flower tent.
