"I required one new tube at the time of visiting the store but i found that the pack of 4 that you sell is great value for money and then i also have spares for any future tube failures. The packaging is great as it really protects the tubes in the packaging so great for storage of the spares."
"It states that these tubes are 218 mm long. But that depends where you measure them to. They are 218 mm long on the tube but that does not include the prongs. Thus they are longer than 218 mm. and don't fit in other manufacturer's linkable striplights. I thought all T4 6w tubes were the same length! The Robus linkable striplights we have take a tube that is 218 mm long including the prongs! So these tubes are no use at all unless you use them on Halolite fittings!!!!!!!!!!!"
