This is so bright yet uses so little electricity. When you turn it on you can hear a pop sound from it's intensity. The heat sink is good and it is vented to release the excess heat it produces. The light is evenly dispersed even on the top. I can recomend this with absolute confidense. But make no mistake this is not your average light. Great for garages and comercial applications. If you are hit by over whelming electroc bills from lighting then this is your solution for very bright light and low cost. I feel the amount you can save on energy cost will pay for the light in a short time depending on usage hours. Even with occasional use it will be benificial to you and the economy and ecology. Don't wait, order yours today, I'm glad I did..
