Product Description
The Best EMI-Suppressed RV LED Bulb
The NK921-350CW stands as the best and only EMI-suppressed LED bulb in the RV market today. If you want a world-class, USA-designed, and patented original RV LED bulb created by “GREGG WILSON DESIGNS”, you have come to the right place. As one of our best-selling RV LED replacement bulbs, this premium unit features a patented LED array that delivers a bright 350 lumens of cool white light (6400K–6600K) while protecting your electronics.
NK921-350CW Voltage & Power Management
We build the NAKED-BULB® NK921-350CW with the finest LED lighting technology and materials available. Our team engineered a wide 8-20 Volts DC range specifically to withstand the severe voltage fluctuations common in a modern RV deep-cycle battery system. This wide-voltage design actively protects your investment from power surges that easily damage ordinary LED lights. Furthermore, it maximizes energy efficiency by operating on only 4 Watts of electricity.
The NK921-350CW Advanced Swivel and Cooling Technology
The clear bulb housing manually swivels to provide maximum light directional control right where you need it most. This allows you to easily adjust your interior beam angles for reading, cooking, or general cabin tasks. Additionally, it utilizes our patented “Flow-Through Vented Clear Housing” to promote a much cooler-running bulb. Buyers can see this structural engineering directly through the clear plastic shell, which hides nothing from view unlike standard, enclosed bulbs.
Bright and Eco-Friendly Performance
This highly efficient unit produces 350 lumens of bright, comfortable Cool White light for your RV interior. Because we focus on eco-friendly performance, this premium bulb contains absolutely no mercury and does not emit harmful ultraviolet (UV) light. Consequently, these long-lasting LED bulbs deliver an incredible life expectancy of 60,000 hours or more, lasting many times longer than the incandescent bulbs they replace.
T5 Wedge Base Compatibility
Finally, the bulb base utilizes a standard Wedge T5 Base (921 Type) connection. This saves you valuable time and money, especially when replacing old incandescent bulbs in those notoriously hard-to-reach ceiling fixtures. We manufacture the NK-921-350CW LED bulb to strict heavy-duty standards, allowing the NAKED-BULB® to easily withstand the daily shaking, bumps, and vibration of a modern RV without failing.

This highly versatile base easily replaces the following common bulb types:- 901, 904, 906, 908, 909
