Sold as replacement bulbs for Ryobi 18V One+ torches. The first bulb burned out and went out in less than 10 uses in a few days. Exactly same experience with bulb #2. Didn't bother #3 & 4. These bulbs suck - they are so bad that Revane immediately refunded my card and said don't bother returning the rest, they don't need them. Absolute rubbish, sure. And Revain knows this - they should ban this manufacturer.
