TCP Dimmable 5W 12V MR16 - 3000K, 40 Degree LED Bulb has a small heat generation and subdued protective housing that functions well in display, recessed, track, and even sensitive lighting applications such as art galleries. Can also be used outdoors, since it is UL listed for use in damp and humid environments. A 3000K color temperature improves the aesthetic while a 40-degree flood beam concentrates the light on a desired focal point. The 5 watt LED is an energy efficient and long lasting replacement for the 35 watt conventional incandescent bulb. LED bulbs are a great investment that will cut back on the costs of replacement bulbs and maintenance with their long 25,000 hour lifetime.
