Highlights High Output Suitable for fixtures with electronic ballast Excellent energy efficiency Cool white - 4000K Plug and play Beam angle of 160º Quick return on investment High Output This Philips LED tube combines its High Output (HO) with excellent energy efficiency. In fact, its lumen-to-watt ratio is about 50% better than that of a standard fluorescent tube. Suitable for fixtures with electronic ballast This T8 tube is 150 cm long and has G13 caps (the same as standard T8 fluorescent tubes). It's designed to work with fixtures that have an electronic ballast meaning no starter is required. Excellent energy efficiency This tube only uses 20 watts of power to replace a fluorescent tube that uses 58 watts. That means energy savings of more than 60% which is why this tube has an A++ energy label. Cool white - 4000K This LED tube has a colour temperature of 4000K which means it emits a cool white light. That makes it ideal for use in spaces like offices and classrooms because this colour temperature aids alertness and concentration. Plug and play The Philips LEDtube HF HO can directly replace its fluorescent equivalent. Simply remove the old tube and insert this one in its place. Beam angle of 160º Conventional fluorescent lighting distributes its light over 360° and that includes areas where it's not needed. This tube, on the other hand, distributes its light over 160° which means it doesn't waste any power distributing light where it's not needed. Quick return on investment This LED tube is so efficient that you'll see a quick return on your initial investment thanks to the savings in energy costs. It has a lifespan of 50,000 hours too and for extra peace of mind, an all-in warranty of 5 years is also included with this product.
