"Bought this to replace a cheaper unbranded 38w bulb that came with the fitting which had started to blacken only a couple of months after fitting. This bulb comes on straight away and is much brighter than the old one. A great product at a great price. Can't really comment on reliability just yet hence the 4 stars for that category."
"I got these for a block of flats that I am responsible for and they are the best value that I could find. They are also the genuine Sylvania make. I always find Screwfix good value, their service excellent and their staff very helpful.
I would certainly recommend Screwfix and will use them again for similar products."
"It was bright when installed but disappointed with its reliability. Bought it in July 2014, and has just failed (March 2015). It was used in a domestic bathroom with moderate usage We might have been unlucky but will buy another make now."
