For a 5 foot tank, you might need another viparspectra unit but place them perpendicular over the tank. These things are only slated for 2x2 foot areas and you're mounting higher up. BRS tested at that mounting height and recommended 100% blues and 30% whites.
Thanks for the refresh I couldn’t remember. I built the bracket for these, and built it for 2 lights so it’s staying until I can afford something better. Plus I had already owned these from a freshwater planted tank I did.

Hello! New reefer here, not new to tanks. I’m using 2 vipers for now. Currently set at 20blue and 2 white @18” above water. No coral yet still cycling. Just looking for % advice but everyone seems to be all over the place. 100 gallon tank, 5 feet long, 18” deep,” 20” tall
Any input is appreciated
That seems good to me until it matures up a bit.
White especially helps the ugly stages, low light, low phosphate is a big help in reducing the amount and length of time it stays.

I’ve never moved my whites higher than 5% ever and during the first 6 months, 10%blue, started ramping up blues 10% a month and stopped at 80% and 3%. Never touched them in the following 2 years.

Below is two, Vipers over a 65g, 3 years old.

Only once when installed.
At 14” above the water, 100% both channels under the lights was 650-700 PAR.

At 14” above the water, 80% blue and 3% white was 250-350 PAR at the surface and at the bottom, 24” down, 80-100PAR.

But I ran two over my 65g.

Do you all think that three 165 watt units over a 2ft x 4ft x 30in tank is overkill? I added the third unit awhile back because of the height thinking two wouldn't get enough par at the bottom and because I wanted more even spread.

Those lights aren't run at 165w
At best 110.
Normally almost dimmed to 1/2 if that if run blue heavy/ white low.

Figure accordingly.

Hey Guys, really awesome thread! Thank you for so much information.
I bought the viparspectra 165w for my 112L (30g) standard tank which is 80 x 35 x 40cm (31 x 13 x 15 inch).
Before i had a red sea reef led 50 over the right side and a fluval nano 20w over the left side of the tank.
The viparspectra is ~10inch above waterlevel, cant get higher cause of ceiling height.

I got a dark spot on the left corner of the tank, i think i will just remove the lenses for better spread.

Since my corals are used to the Reef LED 50 on full power, do you think i can start with 40% on blue with the vipar? The tank seems really dark overall compared with the 2 lights before.
