Highlights Energy savings of up to 70% Replaces 18 watts LED starter included Warm white - 3000K 5-year all-in warranty Energy savings of up to 70% This Osram SubstiTUBE Advanced LED tube is 60 cm long and offers energy savings of up to 70%. That means lower energy bills over its entire lifespan of 50,000 hours which amounts to almost 20 years with normal use! It has the best possible energy label of A++. Replaces 18 watts When changing from fluorescent tubes to LED ones, it's important to check the length of your current tube as well as its wattage. While the length needs to be the same, the wattage will be different. That's because LED tubes are far more efficient and produce the same amount of light using less power. This LED tube only uses 7.5 watts of power to replace a fluorescent tube that uses 18 watts, for instance. LED starter included The Osram SubstiTUBE Advanced UN LED tubes are universal which means they work with (G13) fixtures that have electronic ballasts as well as ones that have conventional ballasts. Fixtures with conventional ballasts also require a starter and one is included with this tube. Warm white - 3000K This Osram LED tube has a colour temperature of 3000K and emits a warm white light. It's perfect for lighting public spaces like hallways and stairways, for instance. The tube has a beam angle of 160º and a score of 80-89 on the colour rendering index means colours are shown accurately. 5-year all-in warranty This product is covered by an all-in warranty of 5 years. If you're looking for an energy-efficient LED tube that will serve you well for years to come, the Osram SubstiTUBE Advanced UN is an excellent choice.
