My pool has a single pool light with an R40 400W incandescent bulb. The light is adequate, but I've changed the bulb/seal twice over the years, and it only seems to last a short time (given the relatively infrequent use it gets). Last season I put a new bulb in and it was dead by the end of the season ! I've not pulled the unit to see if it leaked, but I suspect the bulbs are just ****. Is there a longer-lived solution out there ? I'm not ready to drop hundreds of $$$ on an LED system, but are there any better options than just rolling the dice on another R40 incandescent ?
