The Commercial Electric 4 in. Color temperature select LED downlight is an easy way to upgrade your existing can lights to the sleek look of recessed lighting and LED energy efficient technology. These LED downlights are compatible with most dimmer switches and are equipped with a unique color temperature CCT changing technology. Now you can select your color temperature depending on your needs or preferences with the flip of a switch located on the back of the downlight. Test different color temperatures before installation and never be dissatisfied with CCT again. Color temperature of these LED downlights ranges from Warm White 2700K to Daylight 5000K, with three options in between: Soft White 3000K, Neutral White 3500K and Bright White 4000K. Using only 8.5-Watt of energy but produce brightness comparable to a 65-Watt incandescent bulb, these LED downlight bulbs are estimated to cost only $1.36 per year to operate. Additionally, these LED downlights are rated to last for 50,000 hours or approximately 34 years. That is 50 times longer than a traditional incandescent BR30 lightbulb, which these downlights are used most commonly to replace.
