Spider LED 柱頂燈 - TP500 系列，39000流明，5000K，AC 277-480V，適用於商業專案

We swapped out the old fixtures in our warehouse lot for these and the difference is huge at 39000 lumens. Coverage is even across the whole parking area with no dark spots between poles, and running them on 277V was straightforward.

Installed four of these in our distribution center lot and the light spread across the whole area is really even, no dark spots between poles like our old fixtures had. Output is bright for 5000K, maybe a touch harsh right underneath, but for a commercial lot it does the job.

We mounted six of these on 277V and the 5000K light is crisp without being harsh on the parking lot. Only gripe is the install weight, definitely a two-person job up on the pole. Coverage across the lot is even, no dark patches between posts.
