Looks to me there is zero advantage, other than being able to say you are using LED's?
Oh! And btw, I sent a msg to the folks at poolcenter.com with pics of our niche (showing numbers) and asked if we could just get the lens, or if there were any other economical solutions.
The reply I recd:
"There is allot of light niches out there. Lights are not something that is easy for a DIY project. Electricity and pool lights are something you should advise a pool tech to install. They are also expensive to replace. There are some nice upgrades to low volt and LED lights on the market now."
Gee, that was helpful. Lol!
