Description
Every switch start fluorescent fitting needs a starter, and this is the FSU type, rated on the pack for tubes from 4W up to 65W. That one span covers the short tubes used in under cupboard and cabinet fittings as well as the long battens found in garages and workshops, so a single part number stands in for several. The body is white, with two pins on the base that drop into the starter holder and lock with a quarter turn. Two starters come on one blister card.
Starters belong to switch start gear, the kind of fitting that blinks once or twice before the tube settles. Kitchen and utility battens, garage strip lights, loft and cellar fittings, shed and outbuilding tubes and older commercial battens are all typical homes for one. If a fitting runs high frequency electronic control gear there is no starter holder in it at all, so check the fitting has a holder before ordering. Where a tube is being replaced, many electricians change the starter at the same time, since a tired starter makes a new tube work harder on every strike.
It is not dimmable, and a switch start circuit is not a dimming circuit in any case, so the starter plays no part in light level control. No IP rating is stated by the manufacturer. Each card carries two starters, and the minimum order is 20 cards in multiples of 20, so the smallest quantity that leaves here is 40 starters, which suits a maintenance store or anyone looking after a run of battens. Fit one by pushing the pins into the holder and turning a quarter turn clockwise until it seats, having first isolated the supply at the consumer unit.

Frequently Asked
Which fluorescent tubes will this starter work with?
Any switch start fluorescent tube rated between 4W and 65W, which is the range printed on the retail pack. Check first that the fitting actually has a starter holder in it.
How many starters do I get, and what is the minimum order?
Each blister card holds two starters. The minimum order is 20 cards in multiples of 20, so the smallest quantity that ships is 40 starters in total.
How do I fit one?
Isolate the supply first, then push the two pins into the starter holder and turn a quarter turn clockwise until it seats. Turn it back the other way to remove it.
How can I tell whether the starter or the tube has failed?
Repeated flickering, a glow only at the tube ends, or a tube that keeps trying to strike usually points at the starter. Heavy blackening at one end points at the tube itself.
Does the manufacturer state an IP rating for this part?
No. No IP rating appears in the specification or on the retail pack, so none is listed above and we make no protection claim for it.
Is it dimmable?
No. It is listed as not dimmable, and a switch start fluorescent circuit is not dimmed by changing or altering the starter in any event.
