Keystone KT-LED54PSHID-EX39-8CSB-D – Frequently Asked Questions

1) Will a Keystone KT-LED54PSHID-EX39 LED lamp screw into my existing 250W metal halide fixture?
The Keystone 54W LED HID replacement uses an EX39 mogul base, which is the base a 250W metal halide lamp sits in. It is rated as a 250W MH equivalent. One thing to settle before you order: this is a ballast-dependent lamp (Lamp Technology B), so it runs on line voltage at 120-277V and the existing HID ballast has to come out or be bypassed. If you leave the ballast in circuit, the lamp will not run.
2) Do I need an electrician to install a Type B ballast bypass LED HID lamp, or can maintenance staff do it?
This is line-voltage work inside the fixture, not a lamp swap. The 54W Keystone HID replacement is a Type B lamp fed 120-277V direct, so someone has to open the fixture, remove or bypass the metal halide ballast, and land the sockets on line voltage. In most commercial and institutional buildings that is licensed electrician work. If you want a change-the-bulb-and-walk-away retrofit for your in-house crew, you want a Type A (ballast-compatible) lamp instead, not this one.
3) Can I put this 54W LED HID lamp on a dimmer?
No, not on a standard dimmer. The lamp is step dimmable, meaning the output changes in fixed increments via the selectable power settings rather than smoothly on a 0-10V or phase-cut control. There is no wireless or networked control built in either. If your spec calls for continuous dimming or a lighting control system tie-in, this is the wrong lamp for that opening.
4) How many lumens does the Keystone 54W Power Select HID replacement put out at each wattage setting?
Three settings, and the output does not track wattage the way you would expect: 7300, 7800, and 7500 lumens across the 54W, 45W, and 36W steps. Color temperature is separately selectable at 3000K, 4000K, or 5000K. CRI is greater than 80 at all settings. Set the switches before the lamp goes up in the fixture, because on a high-bay or a pole head you are not getting back to it easily.
5) Can I use one LED HID lamp across a warehouse, a parking garage, and an office corridor instead of stocking three SKUs?
That's the point of the selectable build. Model KT-LED54PSHID-EX39-8CSB-D carries three power levels (54/45/36W) and three color temperatures (3000K, 4000K, 5000K) in the one lamp, so a property manager or MRO buyer can stock a single part and set it to 5000K for a garage, 4000K for a warehouse aisle, and 3000K where a warmer look is wanted. Same base, same EX39 socket, same 120-277V range everywhere.
6) Will this LED lamp light the whole fixture or leave a dark spot under it like some corn lamps?
Beam angle is a full 360 degrees, so the Keystone 54W HID replacement throws light all the way around the lamp body rather than in one direction. That suits it to open reflector fixtures, shoebox heads, wall packs, and high bays where the original metal halide lamp radiated in every direction and the fixture reflector did the aiming. In a deep enclosed or gasketed fixture, heat around the lamp is the thing to watch, not the distribution.
7) How long before I have to get the lift back out to change these lamps again?
Rated life is 50,000 hours. On a warehouse burning roughly 12 hours a day that is a bit over 11 years, against the 10,000 to 20,000 hours typical of the metal halide lamp coming out. For a facility running lifts or bucket trucks for relamping, that relamp interval is usually where the money is, not the wattage.
8) How much does a 54W EX39 LED HID replacement lamp weigh, and will my existing socket hold it?
The lamp weighs 2.1 lbs. That is well under the 250W metal halide lamp it replaces, so an EX39 mogul socket that was carrying the original HID lamp is not being asked to do more. In a pole-mounted or pendant fixture that gets vibration, the lighter lamp is easier on the socket shell.
9) What is the actual part number to order for the Keystone 54W Power Select Color Select EX39 lamp?
Order Keystone KT-LED54PSHID-EX39-8CSB-D. That single model covers all three wattages and all three color temperatures, so there is no separate part number per setting. A distributor quoting this only needs the one number.
