Fluorescent light is a powerful tool in your True refrigerator, merchandiser, or freezer. Fluorescent light bulbs, like the True 841011 by Sylvania (L15W/21-840 Plus), provide light in your appliance without warming the refrigeration compartment. A traditional incandescent bulb large enough to light your commercial cooler would get very warm and force the refrigeration system to work hard to keep the temperature low. The 841011 lamp is a cool, bright fluorescent bulb that is a cost effective way to light your appliance, keeping visibility high and energy consumption low.
