Keystone KT-WPLED55PS-M4-8CSB-VDIM – Frequently Asked Questions
1) Can the Keystone KT-WPLED55PS wall pack replace a 250W metal halide wall pack?
That is the swap it is built for. Keystone lists the KT-WPLED55PS-M4-8CSB-VDIM as a 250W metal halide equivalent, drawing 55W at its top setting and putting out 7500 lumens. Step it down and you get 45W/6300 lumens or 35W/5000 lumens, so you can dial the output to match the old fixture's real light level rather than its nameplate.
2) What color temperatures can I set on the Keystone KT-WPLED55PS wall pack?
Three: 3000K, 4000K and 5000K, selected on the fixture. That matters if you are adding fixtures to a building that already has a mix, you set the new unit to match instead of ordering a specific CCT. Color rendering is above 80 CRI at any of the three settings.
3) Does this Keystone wall pack need a separate photocell for dusk-to-dawn operation?
No. A photocell is part of the KT-WPLED55PS-M4-8CSB-VDIM, so it turns on at dark and off at daylight with no external control or timer wired in.
4) Will this wall pack run on 120V and on 277V circuits?
Yes, it accepts 120-277V, so the same fixture works on 120V residential-style branch circuits and on 277V commercial lighting circuits. Useful if you are standardizing one part number across buildings with different service.
5) Can the Keystone KT-WPLED55PS be dimmed, and what controller does it need?
It dims on a 0-10V signal, which means a low-voltage dimming pair run back to a 0-10V compatible controller or panel. It will not dim on a standard line-voltage wall dimmer. If you are not dimming, the fixture still works, the control leads just get capped.
6) Does the KT-WPLED55PS come complete, or do I order an LED module separately?
The wall pack is a complete sealed fixture, not a retrofit kit, so there is no separate LED module or accessory to order with it. You supply the branch circuit wiring, the mounting box, and 0-10V control wiring only if you intend to dim it.
7) How long is this LED wall pack rated to last before relamping?
Rated life is 50,000 hours. On a photocell running roughly dusk to dawn, that is well over a decade of nightly operation, which is the maintenance argument against keeping metal halide heads that need lamp and ballast service.
