light placement

[winzig]

good day fellow reefers I have something g I need help with
I have a 100g tank 72"x18"x18" and I have four kessil tuna blue lights and I need help with the spacing of the lights.
I can not find much about this topic.
any ideas would be much appreciated
cheers

Welcome to your new home for saltwater reef aquarium resources and fun! Welcome to the family!

That's a nice wide aquarium. Are you planning on putting them on the glass, or hanging them, or another option?

 

[Crabs McJones]

Welcome to R2R! Are they the wide angle lights or narrow angle lights

wide

I'm an evenly spaced kind of guy, i say hang one every 18 inches about 10" off waters surface

I would probably do 72" / 5 (spaces) So that would be 14.4" apart if you wanted them spaced evenly

I only have 4 lights

 

[Marinus]

I was thinking though...

[Glass] <- 14.4" -> [Light] <- 14.4" -> [Light]<- 14.4" -> [Light]<- 14.4" -> [Light] <- 14.4" -> [Glass]

[Glass] <- 14.4" -> [Light] <- 14.4" -> [Light]<- 14.4" -> [Light]<- 14.4" -> [Light] <- 14.4" -> [Glass]

nice I get it thanks

 

[Marinus]

No problem, I hope your lights turn out great

 

[Marinus]

nice I get it thanks

I was just thinking though, if they are all exactly spaced you might have more par where 2 light outputs overlap and less on the edges. If you space them out another inch or so farther apart you might have a little more even coverage towards the edges.

Crabs McJones idea works out well for even spread!

[Glass] <- 9" -> [Light] <- 18" -> [Light] <- 18" -> [Light] <- 18" -> [Light] <- 9" -> [Glass]

16" apart at 10" above tank top

Welcome to R2R. which model kessels do you have?

 

[Michael71]

The 500's can illuminate up to 36" wide per kessel's specs

[Glass] <- 9" -> [Light] <- 18" -> [Light] <- 18" -> [Light] <- 18" -> [Light] <- 9" -> [Glass]

This is the way... Unless you intentionally want to make some lower light areas on the ends for lower light corals.
