Side By Side Lights

All lighting fixtures note the maximum wattage light bulb that should be used. Here, the maximum wattage is marked with a sticker, left. Using a light bulb with more wattage than the maximum denoted could damage the wood surrounding the lighting fixture and create a fire hazard. Also, look for the UL Mark, right, indicating that the lighting fixture has met the rigorous testing standards of Underwriters Laboratories.
