Highlights MASTER series UO: Ultra Output Energy savings of +57% Long lifespan Suitable for different areas Cool white - 4000K MASTER series The MASTER series EM UO LED tubes from Philips are perfect for those looking for energy-efficient lighting that has a long lifespan. They have an impressive lumen-to-watt ratio and deliver far more lumens per watt than fluorescent tubes. The rotating G13 caps make it easy to install them in fixtures that have a conventional ballast and the starter you need is included too! This T8 tube is 120 cm long. UO: Ultra Output While the Philips High Output LED tubes deliver lots of light, the Ultra Output LED tubes go a step further. In fact, they deliver 15% more light and this tube emits a total of 2500 lumens. If circumstances demand more light, therefore, this LED tube delivers it. Energy savings of +57% One of the biggest advantages of LED lighting is that it can produce the same amount of light as fluorescent lighting using much less energy. This LED tube uses just 15.5 watts of power to replace a fluorescent tube that uses 36 watts, for instance. That means energy savings of more than 57%! Unsurprisingly, this tube has the best possible energy label of A++. Long lifespan The lifespan of an LED tube is much longer than a fluorescent tube too. Whereas a fluorescent tube typically has a lifespan of around 10,000 hours, this LED tube lasts up to 60,000 hours! The combination of energy efficiency and a long lifespan means that you quickly earn back the cost of your initial investment and carry on saving money throughout the LED tube's entire lifespan. Suitable for different areas The Philips MASTER LEDtube EM UO is suitable for use in a wide variety of areas including factories, warehouses, parking garages and transportation hubs. Thanks to its Ultra Output, it's ideal for ceilings that are over 4 metres in height too. This LED tube has a beam angle of 160°. Cool white - 4000K A colour temperature of 4000K means that this tube emits a cool white light that helps to keep people focussed and alert. That's why this colour temperature is often chosen for use in offices or classrooms.
