4-65W Fluorescent Starter - 25 Pack

A fluorescent starter is the small cylindrical component that sits in the starter holder alongside the tube in a switch-start fitting, and this one covers tubes rated 4-65W. That span takes in most of what is still in service, from a short tube over a work surface up to a full length batten in a garage or store room. The job it does is brief but essential: at switch-on it closes a contact so current preheats the cathodes at each end of the tube, then opens it so the ballast throws the voltage spike that strikes the arc. It does that every time the light is switched on, which is why it is treated as a consumable.

That makes a box of spares worth keeping wherever fluorescent tubes are still working: workshops, garages, lofts, utility rooms, cellars, shop back rooms and rental properties with older battens over the kitchen units. Before you order a new tube, check the starter. A tube that flickers without settling, blinks on and off in a slow cycle, or lights only as a dull glow at each end is often reporting a worn starter rather than a failed tube, and swapping the cheaper part first is the sensible move. Fitting one takes seconds with the power off: the starter pushes into its holder and locks with a quarter turn.

There is no dimming here. Switch-start fluorescent gear runs at a fixed output and the specification records it as not dimmable, so pair it with a standard wall switch. No IP rating is given by the manufacturer, so we make no claim about one. You receive one box of 25, and the minimum order is a single box, which is enough to keep a busy workshop in spares through several years of tube changes.

Which fluorescent fittings will this starter work with?

It suits switch-start fittings that use a standard starter holder, and the pack covers tubes rated 4-65W, which takes in most domestic and workshop tube lengths.

How do I tell whether the starter or the tube has failed?

A tube that flickers repeatedly, cycles on and off, or glows only at each end is usually a worn starter, so fit a fresh one before buying a new tube.

Can I use these on a dimmer switch?

No. The specification records this as not dimmable, and switch-start fluorescent gear is not built to run from a dimming circuit, so use a standard wall switch.

Is an IP rating given for these starters?

The manufacturer does not state one anywhere on the pack or the specification, so we claim none. The starter is intended to sit inside the fitting's own holder.

How many starters do I receive?

Twenty five, supplied in one retail box, and the minimum order is a single box, so one purchase gives you a long running stock of spares.
