Halolite Fluorescent Tubes T4 1200lm 580mm 20W 4 Pack is rated 4.6 out of 5 by 35.
Rated 4 out of 5 by from The usual low cost tube. T4 Tubes usually have plastic end caps these days. These are the more familiar crimped end jobs as found on such as T8 tubes. Their packaging is pretty good and the price is too. The only problem I had was length of the tube, all were a couple of mm too long making them difficult to fit to the type of fitting I have.

Rated 5 out of 5 by from Cool white lights Bought these tubes as one of the old tubes had blown. Was going to replace everything with led under lights but fitted these tubes and are great. Same colour as cool white ceiling lights.

Rated 5 out of 5 by from T4 lamp 20 watt 4 pack Unbeatable for the price last for ages gives of a lot of light would highly recommend buying these

Rated 5 out of 5 by from Exceptionally Bright Great Value compared to elsewhere. These were much brighter and had a much whiter light than the yellowish light in the bulbs they replaced. When ordering T4 make sure you get the right width (e.g. 580mm)

Rated 5 out of 5 by from Excellent Value I was quoted a lot more elsewhere so the Screwfix price for 4 bulbs is fantastic value

Rated 5 out of 5 by from Bright light Bought these to replace failed under cabinet light tube. Light is so good my wife wants the others replacing now. Very well packaged and good price.
