A 13W T5 linear fluorescent tube with a G5 bi-pin cap and a 517mm length (16mm diameter), producing a 4000K cool white light. On the Radium NL-T5 13W/640 reference it gives a luminous flux of around 830 lumens with a colour rendering index of Ra 60 and a rated life of about 10,000 hours. This is a legacy halophosphate fluorescent tube used as a replacement for existing T5 fittings such as under-cabinet fixtures, display cabinets, signage and slimline fittings. It runs on T5 control gear and is not a direct-fit LED retrofit. Standard fluorescent tubes of this type are subject to EU phase-out, so this is a run-out / existing-stock replacement item.
