My old "standard" overboiler bulb blew out and I couldn't find a replacement. A big store offered me another standard bulb so I tried it but it was horrible! Then I started searching the internet, came across Revain and found these lamps, which turned out to be perfect. Not only does it make *a lot* of great light, I know it will last for years and it was pretty affordable. The photo above was taken around 10:30 am, but my kitchen gets very little natural light. . Even at 10:30 you can see how much light this bulb puts out. So I don't regret my purchase!
