been said many a times in this thread. that light is perfect match for that tank for a display tank. zero reason to think it wouldnt work a frag tank.... that said. i have in my plans to do the same thing. 300w over a 40B as a frag tank also, but im going to change some of the leds to maximize the use of the light as a frag grow out. alot of 6500k is gonna get changed in. and also going to add some sub 420 on the actinic channel. again im going to use this light simply as a frag light, not a display, so im trying to get the best growth with the best color for the cheapest i can..just a thought

Who sells the LEDs to replace these? I have a few blues that look like they need to be changed.

The warm whites in 2500-6500 have plenty of red and green spectrum in them. Having the red and green leds imo will just add to blending issues aka disco effect.

I just got my lights set up a couple of days ago. They are an older version that I bought about 2 years ago. I noticed that the fans run all the time even at the lowest settings. Do they do that on the newer ones too? It seems unnecessary as the light barely feel warm to the touch.
luckily the fans are quiet.

I have a 120”x38”x29” tank. 29” being the height. I was concidering the 300 watt versions for my tank. Would 5 of these work... one every 2 feet?

this video https://www.youtube.com/watch?v=tCSbukB3Ieg makes a lot of interesting points about these Chinese "black box" lights, to me the most worry-some is their use of super cheap non-UL listed power supplies which may pose a fire hazard, backed up by the fact that they don't seem to be sold by any retailer that one would have a realistic chance of suing if they burn something down
First question: Does anyone know a UL listed intermediate between these super cheap lights and the $650 level lights like the radion XR30w? I am finally thinking of converting over my 31" deep 300 gallon which is mainly lit by 1200W MH pendants and
a couple of T5s and LED strips, I would want a lot of light

The second point the video https://www.youtube.com/watch?v=tCSbukB3Ieg makes about these Chinese "black box" lights is that they have a very focussed beam, with excessively high par values near the center of the beam that fall off precipitously near the edges. Is anyone aware of an equally detailed study of how the par values drop off after a diffuser is put in?
Hey Spartan can you tell me exactly which 3 lights you got and approx cost? Lighting a new 180g and don't think I will have anything but softies.

AI is made by Ecotech. I would look into the Hydra series as they make UL listed power supplies. Unfortunately they are prone to premature failure. However, replacement power supplies are affordable. As far as other companies making UL listed power supplies or drivers? Nope. I think if you fall down the rabbit hole of researching it, you'll find the UL fight a moot point.

I ended up removing all the stock 60 degree lenses...put 90 degrees on half of the leds and left the other half lense-less (for 120 deg spread). The laser beam effect in them middle was greatly reduced...and spread was much better..while still getting enough PAR to the bottom half of the tank.
Overall...just takes some playing around with...but the stock 60degree lenses the black box comes with standard are it's biggest issue IMO.
Hey where did you get the different lenses? How hard was it to swap them out? How high off tank (and what tank) did you mount after the lens change?

Out of the black box models, which would be better for a standard 29 gal. 30"x12"x18" tank. I'm thinking th 300W would be too big and overkill? I'm looking at the WIFI model with 90 degree lens. I'm guessing I would need to remove the lenses and keep it low to the tank? I plan on keeping the rock work to 21" wide.
