How many lights?

Moved from here.
I know this is a really old post, but is the spa not visible in this picture? We are planning to do a 17x38 pool with a 7 foot tanning shelf full width(which leaves 31 feet for the deeper section). PB says 2 lights which there is no way. I was thinking 4, but based on this picture I'm thinking we could easily do one on the shelf, 2 in the 31x17 section of the pool and one in the spa.

Sound right?

Depends on the model lights you intend to use and the lumens it puts out.

Pentair LED Pool Lights - Further Reading

Pentair has a few models of LED lights. They vary in size and type of niche required. The chart above summarizes the light specifications.

Pentair guideline is to aim for 4 lumens per square foot of pool surface. For example, if the pool is 500 sq-ft then you need 500x4=2000 lumens. This would be 4 MicroBrites or 2 IntelliBrite rgb.

Inyo Pools also has a good blog on How Many Lights Do I Need For My Pool? with a table summarizing the coverage of the different Pentair lights.

Jandy has an excellent LED Lighting Design Guide.

Thank you for taking the time to reply. I really do appreciate it.
The Further Reading thread is the one that led me to post I ultimately responded to, but was opened as a new thread instead from the moderator.

I get the chart and based on my calculations of my pool we should have 5 Microbrite lights(38x17 rectangle with a 7x17 shelf) and then one more in the spa.
Based on the picture of the pool in the Pentair Pool Lights thread, the pool should have 3.6 ((31*14*4 )/ 500), but he only has two in the pool area.

I guess what I'm trying to figure out is will I regret only using 2 as well in the pool section for a similar size. Doesn't seem like it and these things don't seem to have a great track record so the less I have to replace in the long run the better.
