Honestly, the amount of light is not diminished enough to be noticeable, and we have a 46,000 gallon pool. Good luck!
Heck, I pulled out my burned out 300 Watt, uber expensive, halogen bulb and replaced it with a 100 watt flood bulb that I had in my bins for 20 years. Less energy and the flood still shoots just fine, all the way to the steps. Shrug.
