旋轉鎖定式光感應器，XALH 系列停車場燈

The twist-lock base made swapping out the old sensor a two-minute job on our 277V lot light. It kicks on right at dusk and shuts off clean in the morning, no flickering so far.

Installed one on our lot light last month and it's been clicking on right at dusk without me touching a thing. The twist-lock base seated firmly in the socket, no wobble like the old one had. Handles our 277V setup fine.

Swapped out two burnt-out sensors and these twist-lock units clicked right in, no rewiring needed. The dusk-to-dawn setting works perfectly on our 277V lot lights, they kick on at sunset and shut off by morning.
