So which one for a 16" wide tank?
That is disgustingly shortSo which one for a 16" wide tank?
15.94 x 16.73 x 15
Have you used either?You may want to up the wattage a bit.. Your Kessil is 15w, most of the others are 30W "class" but this is 60W
Another choice from Amazon CA
NooPsyce is also high wattage.
No.Have you used either?
What light are you running currently?
I build and use fw lights. My suggestions are based on physics, history, how leds work and others experienceWhat light are you running currently?

A80s are a bit pricy for me even... I wanna keep some sps again mainly. I kept acros and montis after 1y of reefing then I had to quit cause I moved. Setting up a tank again and I need higher par since I sold my radion and spent it on cooking equipment
There's someone selling the halo version. Is that different?I have a single Fluval Marine Nano light ($75) on my SPS dominated 10g reef tank and its been growing my corals pretty strongly for the past year. I’m planning on getting a second one tomorrow but it easily puts out 200PAR+ on the sand bed and 100+ PAR on the sand bed with less white intensity. Most other “cheap” lights from Amazon such as Hygger, Aquaknight, Lominie A20, etc all have strong lights but the diffusion and blending in my experience isn’t as good, obviously, as AI, Ecotech, T5, Reef Breeders, etc but the Fluval Marine light might be the answer you’re looking for
I’ll link a photo of PAR values with respective light intensity levels from an old thread on the forum and a photo of my tank.
My corals aren’t showing PE cuz I literally just moved them around and took them out of the tank when I took this photo hahahah but the growth is 100% guaranteed

The halo version is earlier model or Fluval 2.0 whereas the Fluval Nano Marine is essentially Fluval 3.0. They removed the aluminum heat sinks, made it sleeker, and light output much much stronger.There's someone selling the halo version. Is that different?
2 color COB (white/blue) vs small panel (more color choices)There's someone selling the halo version. Is that different?
How long have you been using it?The halo version is earlier model or Fluval 2.0 whereas the Fluval Nano Marine is essentially Fluval 3.0. They removed the aluminum heat sinks, made it sleeker, and light output much much stronger.
I'm actually going to pick up my package from Amazon that is the light and having been in the hobby for quite a while and having most lights from high-end (Radion XR30 Gen 4) to Kessil A160WE to Lominie A20, these lights are probably the light you're looking for!
Once you get a larger tank, then invest in a higher quality light, in the sense of spread and light intensity, but even then not a lot of people run their high-end Radions or Reef Breeder lights beyond 50% intensity unless you have a really tall tank or need to grow SPS on the sandbed.
I run my Fluval Nano Marine at:
Blue, Violet, Cyan at 100%
Pink at 7% but you can lower this (it's just for visual appeal)
White ramp up to 25-35% during peak
(I used the PAR distribution photos from an old R2R thread about the light as a guide)
Year and a half now although I’m looking into integrating T5sHow long have you been using it?
Wait sorry how many are you running and whats the dimensions of your tank.Year and a half now although I’m looking into integrating t5s
