I've a strip light in the kitchen containing 3 Halogen bulbs. 290 lumens / 50W. One blew the other day, but I had a spare. GU10. They get very hot and I've never been comfortable with this. So I've decidedto buy LEDs. Questions are: What LED is compatible with the above on Watts? When the next Halogen fails, will I do any harm by replacing with a LED?
