Kessil Led

[piranhapat]

Any body got these Led Kessil 150/ 350 w. Was thinking on getting 3 for my 90gal would that enough. How hot do they run... Any review or feed back ...

I was going to get the 150 last year but they were sold out i waited 2 months. Never got them. A LFS by me just got the 150 it is nice, seems fairly brite for only 35 watts, runs cool. You would need at least 3 150 and i think 2 350, but i would wait for the 350 it has better par for the depth of your tank, and you can adjust the color on the 350 with a white and blue dimmer, theres no adjustment on the 150. The only downside to them is you cant do some dusk and dawn you would need another strip.

Im waiting for him to get the 350 then i will decide if i want to switch i have a reefbrite strip i can use for dusk and dawn. At the moment i think im going to get 2 of them.

Sounds like 350 w I'll check out too. Their look awesome.....

Based on some of the par readings I have seen I don't think 2 will cut it and question if they're strong enough for tanks more than 20"+ deep.

 

[NewfiDog]

Yeah the 150 isnt to good after 20, they claim the 350 is for 24+. But ive seen the 150 on a 24 inch deep with anenome's and they do well. Havent gotten to see the 350 yet.

Just finished putting these up on my tank in time for the lights to come up. The photos show 4 lights over the tank, My tank dimension is 61-1/2" X 19-1/2" X 15" high. Last photo is with just one on to test for coverage.

Initial PAR #s with lights 6" above water:

Right at surface: ~400 - 425
middle of tank: ~300
On the bottom of tank: ~90-100

If the tank is 15" Tall than these numbers are very umimpressive to say the least. I understand the units are only 35W each but I see these as Nano lights. With those numbers your looking at about 20-30 PAR on the sand bed in a 24" deep tank...And thse are the narrow units

Bobby why are you throwing crap all over their hopes and dreams..

 

[NewfiDog]

Yes thats the 150, kessil dosent recommend over 12 inch on those. I was waiting to see what the new 350 does. As far as i know there is no wide 150 just 350 wide for frag tanks.

You should read Frick's post.. the response from David at Kessil (Sales Manager). With these fixtures, you can't solely rely on PAR readings, esp if they're not equipped with UV meter. I'm getting one for my 20g high nano and probably two a350ws for my 75g build.

Ron who's throwing crap? I didn't post the numbers just going by what I read. And based on that initial post those numbers were not impressive for a fixture costing $300+ dollars. The OP has a 90 gallon tank and asked about coverage. I would hate to see him spend $1000 on lights and find out they don't provide the light needed for his setup. I like the design and the idea and have been looking at A LOT of different LED options for my 120. Sorry my honesty and questioning bothers some people.....:banghead:

So will the 350 be good kn a 120 gallon 48 x24x24 ?if so how many

 

[strgazr27]

I would think 4 for a 120 would be a start of its a 48x24x24. 2 MAYBE on a softie tank.

 

[NewfiDog]

The 350 is suppose to do a 24*24 the 150 you would need 3-4 but like strgazr mentions it doesont have good par at that depth, kessil i beleive only recommends the 150 up to 12 inches the 350 which is 90 watt they claim is for tanks 24+ inches but they just came out a few days ago so i havent seen any kind of par readings.

 

[strgazr27]

From testing NeptuneAquatics did. Not bad numbers but you'll obviously have fall off on the perimeter..

The A350 comes with a 31-degree (62-degrees edge to edge) reflector and delivers a stream of intense focused light that can penetrate to the very bottom of a deep tank. This model is recommended for users with tanks deeper than 24? or for reefers who have corals with high intensity lighting requirements.

A350 PAR VALUES WITH LIGHT 6" ABOVE THE WATER AND MEASURED FROM LIGHT TO SENSOR:

12" from light to sensor: 475 (sensor 6" below water line)
18" from light to sensor: 250 (sensor 12" below water line)
24" from light to sensor: 225 (sensor 18" below water line)

That 225 is 18" deep. I'd imagine it would be around 150-175 at 24" below the water line...

i just ordered the 360's they just came out with them, difference is you can adjust light intensity!!

So will the 350 be good kn a 120 gallon 48 x24x24 ?if so how many

2 x 350 Narrow beam for acros

2 x 350W wide beam for more lps softies.
