Highlights High Output Energy-efficient replacement Quick return on investment Easy installation Beam angle of 160º Daylight - 6500K High Output An LED tube is able to provide the same amount of light as a fluorescent tube using far less energy. This Philips LEDtube EM High Output, for instance, has a lumen-to-watt ratio of 159 which is almost double that of an average fluorescent tube that only has a ratio of 85. Energy-efficient replacement Replacing a fluorescent tube with an LED one means excellent energy savings. This LED tube uses just 18.2 watts to replace a fluorescent tube that uses 58 watts and that means energy savings of more than 65%! No wonder it has the best possible energy label of A++. Quick return on investment Even though LED tubes are a little more expensive to buy initially, the cost can be quickly earned back due to better energy efficiency. This is often within 2 years (depending on use) and, of course, you'll continue to save money throughout its entire 50,000 hour lifespan (+/- 15 years)! It's also covered by an all-in warranty of 5 years. Easy installation This LED tube has the same G13 caps as a fluorescent one which means it can be used as a direct replacement. Note that it's only suitable for fixtures that have a conventional ballast and even comes complete with the starter you need! This tube is 150 cm long. Beam angle of 160º Fluorescent tubes distribute light over 360º which means light is also directed upwards where it's not needed. This LED tube, on the other hand, has a beam angle of 160º. This means light is only directed downwards and to the sides where it's needed most. Daylight - 6500K This tube has a colour temperature of 6500K which is similar to daylight. That means it's suitable for professional and personal environments where lots of light is needed.
