Save energy with these double-ended tubular LED double ended DET tubular light bulbs. Fitted with a SCC-S15 round (15mm) cap to both ends. Designed to replace traditional 30W fluorescent tubes found in shaver lights, concealed lighting and picture lights, these LED tubes offer the same brightness, but use only a fraction of the energy. The tubes are 221mm in length, and are simple to install, as their single contact S15 caps retrofit to existing furnishings. Simply remove your old, high-energy light bulbs and fit these energy-saving replacement light bulbs in their place. They emit a bright 410 lumens of cool white 4000K light, perfectly suited to display and task lighting, and their opal finish offers a softer light with reduced glare. Their long 15,000 hour life means that once they're installed, it will be years before they need replacing again, which is particularly useful if they are fitted in a difficult to reach location. Unlike traditional fluorescent tubes, these DET light bulbs contain no hazardous materials such as mercury, so they are safer to handle and easier to dispose of.
