I have typical security light with 2x PAR38 globes and I was thinking the replace the whole unit with LED one (2x 10W).
Do you reckon I can pretty much pull off the existing light and hook up the new light with existing wires? Thanks!
I usually find the lamps outlast the sensors on those cheap dual flood light sensors so probably replace the whole thing.
The parts that go on the wall are not a standard, you need to use the one that comes with the new sensor or it will not seal properly, so dont just go pulling the front off and assume that since the screws are in the same place its all good to go on the back half already on the wall. I did and got the LED par lamps filling with water.
Theoretically yes, if you're comfortable working with mains wiring. Or, you could just replace the PAR38 globes with LED equivalents.
I replaced the PAR38 100W lights that the previous owners had installed with LED ones, just needed to wrap a collar of foam around the neck to keep bugs out since it's a smaller diameter neck, but apart from that it's been fine. That's the easiest way to upgrade.
