Review on High-Performance Pack 13 Watt Double Tube: Efficient Lighting Solution by Troy Jennings

Matches our lamp perfectly. Existing lightbulbs were nearing the end of their lives - it would take a minute or two to go from dim to full brightness. I ordered these lamps which arrived ahead of the scheduled delivery date, fitted them in less than a minute and voila, instant bright light at the touch of a button. I ordered four packs so I'll have a replacement set in about a year. Great price, very satisfied!
