Very bright bulb for my desk lamp. It has transformed my working practices. Now I look forward to sitting down at the desk to get on with things.

Finding a replacement bulb at a decent price, I thought was going to be tricky. Turned out not to be!

Bulbs are great, just as bright as original ones that came with light fitting. Not easy to comment on life of bulb as they've only been in use for 2 or 3 weeks. Great prive and service.
