Yes, 110V, I can run it with the pump off one GFCI no issues.
The fitting is about 1/64th smaller than typical, I put a shutoff directly on it by scarring it up really good and using a ton of glue - no leaks 3 yrs later, so it must have worked well.
I'm still looking into the LED version of it but it's expensive - if possible, I'd like to get that or retrofit my own - I've got a lot of experience with LED's, so setting that up should be relatively simple.
Guess I'll just wait til the bulb blows, then i have a csing to play with....
