This 12V or 24V FC8T9 LED replacement It is a simple and easy way to get a much brighter light which starts instantly, even in sub-zero temperatures.  It doesn't produce RF interference or attract bugs the way fluorescent bulbs do.

Internally driven LEDs bypass the ballast in your existing fixture to reduce power consumption. This is easy to do, and takes only a few minutes.  See Installation Instructions here. Without a ballast to fail, you can expect worry-free operation for years of use.

Circline tubes are used in many older boats and RV's - Irwin, Gulfstar, and Sailmaster Yachts, as well as Wanderlust RV's.  These LED tubes are a direct replacement for Thin-Lite 109C fixtures and RGM Industries 9" x 9" fixtures with 8" circular tubes.  If your thin-lite or RGM ballast has failed, now is the perfect time to switch to LED.

NOTICE: While the original ballast must be bypassed, it need not be removed. Our bulb includes wire pigtails for a simple retrofit.

    Can't imagine how this could have been easier - old tube out; quick splice into power; new tube in; done. Ample light over galley in my '89 cruiser - loving it!
