The LED's are configured for maximum light output and the highest efficiency so the internal power supply is not dimmable and the cover over the LED's is clear.

LED's have become a popular investment because of the immediate savings in electricity but LED's offer more advantages. There is no delay or flicker at start up, LED's provide full brightness immediately. Fluorescent bulb manufactures are beginning to publicize the fact that in order to reach the bulb's life expectancy, you must turn the bulbs on for a minimum of 3 hours or you will see a shortened service life.
LED's do not suffer this pitfall. You will not shorten the life expectancy of LED's by turning them on and off many times during the day. LED's are not effected by cool temperatures, LED's provide full brightness even at below freezing temperatures.LED's do not have a "warm up" period. In many areas, scrap metal yards will pay you when you drop off LED bulbs for recycling because of the valuable aluminum heat sink along the entire length of the bulb.
