Keystone KT-MSLED44PS-4-8CSA-VDIM 4ft Led Microstrip Fixture

Product Description

The KEYSTONE KT-MSLED44PS-4-8CSA-VDIM is a 4-foot LED microstrip fixture with field-selectable wattage and color temperature. Electricians and lighting contractors can set the output at 44W, 28W, or 18W and dial in the color temperature at 3500K, 4000K, or 5000K without stocking multiple SKUs. At maximum output, the fixture delivers 5850 lumens. It operates across a wide voltage range of 120 to 277 volts and supports 0-10V dimming for integration with standard low-voltage dimming controls. A frosted lens provides even, diffused light distribution suited to occupied spaces.

This fixture is designed for commercial and light industrial interiors where adjustable output and color tuning reduce inventory overhead. Typical applications include office spaces, warehouses, retail back-of-house areas, schools, and utility corridors. The 48-inch form factor fits standard ceiling grid and surface-mount configurations. Electricians installing on retrofit or new-construction projects benefit from the selectable wattage, which allows a single fixture to meet varying footcandle requirements across different zones without fixture substitution. The DLC Standard listing supports utility rebate eligibility on qualifying projects.

Compatibility

Designed as an OEM-style LED microstrip fixture for commercial and light industrial applications requiring selectable wattage and CCT in a 4-foot form factor. No specific compatible model numbers were provided in the product data.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Disconnect and lock out power at the panel before wiring or mounting the fixture. For 0-10V dimming, verify that the dimmer or lighting control panel is rated for 0-10V low-voltage control circuits and that the control wiring is run separately from line-voltage conductors per NEC requirements. Confirm the wattage and CCT selector switches are set to the desired position before closing the fixture housing.
