Possible causes include a worn bulb, a defective starter, or a problem with the ballast or connections. Which method of control is appropriate depends on the type of lighting: classic TL with starter, TL with electronic ballast, or an LED bulb.<\/p>\n<h2>Is it an LED bulb or an incandescent bulb?<\/h2>\n<p>First, check the label on the tube and the available information about the fixture. Note the type and length. Two tubes that look similar don\u2019t necessarily work the same way electrically.<\/p>\n<ul>\n<li><strong>TL with conventional power supply device:<\/strong> Many of these fixtures come with a separate starter.<\/li>\n<li><strong>TL with electronic circuit breaker:<\/strong> This system generally does not have a separate replaceable starter.<\/li>\n<li><strong>Led tube:<\/strong> The permitted power supply differs per model. Some work with a suitable pre-connect device, others with mains voltage according to their own installation specifications.<\/li>\n<\/ul>\n<h2>Recognizing a worn-out TL bulb or starter<\/h2>\n<p>Dark discoloration at the ends of a fluorescent tube can indicate wear. It is not a conclusive diagnosis: other components can also cause start problems. In the case of a fixture with a loose starter, an unsuitable or defective starter can play a role.<\/p>\n<p>Use only replacement parts that match the fixture and the lamp type. A conventional TL starter and a LED starter are not necessarily interchangeable. If the fixture does not have a separate starter, then \u2018replacing the starter\u2019 is not a suitable first step.<\/p>\n<h2>What can you check before replacing something?<\/h2>\n<ol>\n<li>Note whether the flashing occurs only when the device is turned on or also during use.<\/li>\n<li>Check whether the problem is related to one tube or several lights at the same time.<\/li>\n<li>Look for the type of tube and the manual for the fixture.<\/li>\n<li>Switch off the power and let the tube cool down before replacing a user-replaceable lamp according to the manual. Use a stable work surface and avoid pressing on the glass.<\/li>\n<\/ol>\n<p>Do not open the electrical connection section for testing. If the problem persists with suitable replacement parts, or if you see damage or notice smoke, remove the fixture and have a technician inspect it.<\/p>\n<h2>Can you replace the TL bulb with an LED one?<\/h2>\n<p>Yes, if the chosen LED tube fits the fixture and the power supply method. In an EM version, a corresponding LED starter may be required. In an HF version, the electronic pre-connect device must be on the compatibility list of the tube. A direct mains-powered version may require adjustment of the fixture; have that done by a skilled installer.<\/p>\n<p>Length and fitting alone are therefore not enough. Check out the <a href=\"\/en\/categorie\/led-lighting\/tl\/\" title=\"LED strip lighting\">LED TL tubes<\/a> with the data from your current fixture attached. If the fixture is worn or damaged, a complete replacement may be required. <a href=\"\/en\/categorie\/led-lighting\/tl\/\" title=\"LED strip lighting\">LED TL fixture<\/a> a more suitable solution.<\/p>\n<h2>Is that a regular LED bulb?<\/h2>\n<p>A LED light in an ordinary fitting requires a different diagnosis than a fluorescent tube.
