أضواء أعلى العمود - سلسلة TP421 21000 لومن، قابلية اختيار القوة الكهربائية ودرجة حرارة اللون، تيار متردد 120-277 فولت

Installed a few of these in the warehouse and the switchable color temperature is a game changer—finally got the warm glow I wanted over the office area and bright daylight for the loading dock. They're noticeably heavier than the cheap fixtures we used before, which feels like a good sign for long-

The selectable wattage switch saved me from ordering two different SKUs for the shop and the storage bay. Dialed them both to 4000K at 150W and the light is clean and even, no flicker on our 277V feed.

Swapped out four old high bays in our shop with these and the selectable wattage made it easy to dial down to 150W over the workbenches. The 21000 lumens is no joke, whole floor is bright now. Took maybe 15 minutes each to hang.
