G13 T8 18W LED tubes, universal white, 240° beam angle This LED light bulb is especially suited for use in sophisticated lighting tasks, since special attention was paid o a high light output level during its development while simultaneously consuming little. With a consumption of only 18W , it replaces conventional T8 fluorescent lamps with an electromagnetic ballast of up to 36 W. Dank der zusätzlich erhöhten The lifetime of up to 50, 000 hours & the excellent light output stability also decrease maintenance costs, since lamp replacements will hardly be necessary. It can replace existing T8 fluorescent lamps with a conventional ballast (CB/LLB) with no need to rewire the light. Only the starter needs to be replaced by the special LED starter, which is included (see the installation instructions). Characteristics- Particularly wide beam angle of 240°- Very long lifetime of up to 50, 000 hours- Immediate, full brightness no flickering or buzzing- Environmentally-friendly LED technology, mercury-free- Cannot be dimmed- Power factor > 0.9- Existing T8 fluorescent tubes can easily be replaced in a few minutes, no re-wiring necessary when used with a CB/LLB
