Osram 25W R50 Full Glass LED SES Reflector Bulb

It pretty much does what it says on the tin. I got it to use with a desk lamp. Hoping it will last 15 years as it's supposed to.

This lamp was just what I needed for my display cabinet

They are working very well, providing a good bright light. They are bright immediately they are turned on.

Invested in these bulbs, as they have 15 years life on them, so saving money and time, so far so good. No problems!
