Synerji LED T8 glass tubes with a G13 cap for 4ft and 5ft fittings, in 6500K daylight or 4000K cool white. The 18W 4ft tube gives 1,800 lumens and the 24W 5ft tube 2,400 lumens, with a wide 220° beam. They suit homes, garages, workshops and commercial spaces.
Choose 18W or 24W to match your fitting length, then the light colour: daylight gives a crisp white for workshops and garages, while cool white is a little softer for kitchens, offices and shops. For the Economy-range alternative, see the Synerji LED Glass Econo T8 tube.

Good to know
Which size do I need?
Measure the old tube: the 18W tube is 4ft (1,212mm over the pins) and the 24W tube is 5ft (1,512mm). Both have G13 pins and a 28mm (T8) diameter.
Can I dim it?
No. These tubes are non-dimmable; use them on a normal switch.
Daylight or cool white?
Daylight is 6500K, a crisp bluish white; cool white is 4000K, a neutral white. Output is the same for each wattage.
Does it need an electrician?
Yes. The driver is built into the tube and it must be installed by a qualified electrician, who will wire the fitting to suit the tube.
