This unique LED retrofit requires an HID ballast to remain a part of the fixture - DO NOT by-pass the ballast. Simply remove your current 175w probe start (M57) or 175w (M137/M152) metal halide lamp and replace it with the Keystone KT-LED48HID-V-E26-840-S for a quick and easy plug-and-play retrofit option. 

Here are Keystone's, suitable for totally enclosed high bay, low bay and other typical HID fixtures, UL Classified for damp locations retrofit LED bulbs. Part number KT-LED48HID-V-E26-840-S consumes just 48 watts of 120, 208, 240, 277 or 480 volt 60 Hz energy and generates a comparable light output to your 175 watt probe start M57 lamp or 175 watt pulse start metal halide M137/M152 bulb. UL approved for fully enclosed fixtures, this non-dimmable LED light bulb, an LED high bay or low bay lighting retrofit option, will produce 5,400 Lumens of light output.

Click here to see the complete Keystone 48 Watt High Bay or Low Bay LED Retrofit Specification Sheet.

These LED bulbs have a screw-in E26 medium base that easily integrates energy saving LED technology into your standard high bay or low bay lighting format. Each KT-LED48HID bulb is rated for use in either enclosed or open fixtures. Install these retrofit bulbs ONLY in a Vertical, Base-Up Orientation.  The physical dimensions of the Keystone metal halide ballast compatible 4000K cool white LED retrofit are 5.7 long by 4.72 wide. Keystone's Smart Drive LED retrofit bulbs eliminate the need to remove or bi-pass your existing ballast. This plug-n-play direct replacement for metal halide lamps is compatible with most magnetic core and coil ballasts (NOTE: These direct replacement bulbs Do Not Work on Reactor or Electronic Ballasts) and requires no rewiring during installation. Keystone has provided a ballast compatibility chart (see the link below) for guidance when selecting a ballast and lamp combination. Lamps were tested for compatibility with the ballasts shown in the compatibility chart. Ballasts that do not appear on the chart might still be compatible but have not yet been tested. All testing has been performed with a stable main supply. The quality of the local main, existing installation and wiring, as well as different manufacturer versions of the ballasts may affect lamp performance. Since no assurance can be provided regarding these factors, it is a general recommendation to perform a test on-site prior to installing the LED lamps. These NON-dimmable LED retrofit bulbs carry a 5 Year Limited Warranty. Click here to see the Keystone HID to LED Smart Drive Ballast Compatibility Guide.
