Review on High-Performance Pack 13 Watt Double Tube: Efficient Lighting Solution by Robert Gomatham

These LED bulbs were purchased to replace the CFLs in my church lights. About half of CFL bulbs failed due to end of life or bad ballasts. Once we figured out how to get to and bypass the ballasts, LED lights were easy to install and worked really well. We've had them installed for over a year now and none of them have failed. Hopefully we won't have to replace them for a few years.
