I have a 24"L x3"Wx 12" H frag tank would one duo mounted about 2 feet above give enough spread?
I was thinking of two UNOs but seems like only pros available. I do not need high par, water is only 12"

24"x30"x12"H?
I think you'll be happier with Uno2 Pro. It's the latest generation, more power with interchangeable reflectors.

You could mount 1 Uno2 Pro high enough for 36"x36" spread but if light spill out the front and back is unsightly, then 2 Uno2 Pro would be better. Also if SPS becomes large colonies, 2 Uno2 Pro would be better for extra overlapping coverage.

No colonies it is a frag tank. It is in my basement fish room.
I'd go one uno 2.0 if cost is a factor and you'll be keeping frags pruned to avoid self shading. Worst case, you could make some kind of shade to keep the light spill down.

PSA: Do not plug in your ReeFi into powerbar controller such as Hydros, GHL, Apex, etc. When relay switches on other devices switch off, I can create power surge to the other outlet that are still on, and these powerbars do not isolate the outlets. I have seen 5 ReeFi Uno 2.0 Pro that have been damaged by power surge. Best is to plug the ReeFi directly to a surge protection power stripe.

They should have at least put MOV (varistor) to prevent induction backfeed.
The fixture or just the power supply are getting damaged?

Both got damaged.
Question about the 395/400 nm LEDs. What keeps them from premature failure/burning out? Seems many manufactures stay away from LEDs in that range to avoid premature failures. I have seen burnt leds and burnt lenses in many fixtures once they go that low. For example those are generally the first to go in orphek lights, black boxes for sure, even eco tech and Ai have burnt lenses in reviews and forum post.
@ReeFi Can answer better, but top level binning, overkill cooling and no lenses all help. I did get some browning on the white plastic Reeflectors when I ran the uv at 100% for 12hrs a day. Actual UV-A is going to degrade plastic near the diode. Just a given. The front cover is glass and won't melt like lenses do.

Occasionally we can get duped by LED manufacturers/vendors giving us cheaper LED chips than specified, which can not withstand no term use of UVA. If this happens generations after generations, then it could be they choose to use the cheapest UV LED chips available which are not designed to last from the materials used.
