Does anybody know because this says 730mm, will it work in a k40? The seller says it does but k40 tubes are around 700mm. Also does it have the right connectors a either end. Many thanks

I don’t have an answer. but some K40 are fitted with a 35W.

Fwiw mine is 720mm end to end.

Plenty of room in mine.
