It unscrews with a quarter turn. On electronic ballast setups, there is no separate starter: it is integrated into the ballast.

Always measure the old tube and the distance between the sockets before ordering.\"}},{\"@type\":\"Question\",\"name\":\"Is it possible to replace a neon tube with an LED tube?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Yes, provided you respect the supply of the fixture. A ballast-compatible LED tube replaces the fluorescent without modification. A direct-supply LED tube requires removing or neutralising the ballast and starter. The base and length must match, otherwise the tube will not clip in.\"}},{\"@type\":\"Question\",\"name\":\"How to wire an LED neon without a starter?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"Cut the power, remove the tube and the starter, then identify the ballast. On a direct-supply LED tube, the ballast is removed or bypassed and the mains reaches the sockets directly. This wiring involves 230 V: have it done or checked by an electrician.\"}},{\"@type\":\"Question\",\"name\":\"Where is the starter in a neon?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The starter is a small cylinder housed in the fixture, near one of the sockets, sometimes under a cover. It unscrews with a quarter turn. On electronic ballast setups, there is no separate starter: it is integrated into the ballast. Cut the power before any handling.\"}},{\"@type\":\"Question\",\"name\":\"Why is the LED neon not working?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The most common causes are a tube not properly engaged in its sockets, wiring that still assumes the ballast when the tube is direct-supply, or a fixture with no power. Check the fitting and the base first, then the supply. A persistent fault calls for a check by an electrician.\"}},{\"@type\":\"Question\",\"name\":\"How to change a neon tube with an integrated ballast?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"On a fixture with an integrated ballast, the tube is removed by turning it a quarter turn, without dismantling the ballast. The replacement then depends on the tube chosen: ballast-compatible, it fits directly; direct-supply, the ballast must be removed. Cut the power before the operation.\"}},{\"@type\":\"Question\",\"name\":\"What is the difference between a T5 neon and a T8 neon?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"text\":\"The T5 measures about 16 mm in diameter with a G5 base, the T8 about 26 mm with a G13 base.

A waterproof tube or a closed wall light limits splashes.
