It even comes complete with the starter you need. It has the same G13 caps as a fluorescent tube and can be used as a direct replacement. Cost-effective LED replacement The CorePro series contains the most affordable products in Philips' LEDtube series. That's why they're an excellent cost-effective LED replacement for fluorescent tubes. The price may be lower, but the quality is still high with a lifespan of 30,000 hours and an all-in warranty of 3 years included in the price. Energy-efficient alternative This LED tube only uses 18 watts of power to replace a fluorescent tube that uses 36 watts. Not only is it 50% more efficient, but it doesn't contain any hazardous gasses either which makes it even better for the environment. It should come as no surprise that this product has an A+ energy label. 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 the overall lifespan of 30,000 hours means you'll carry on saving money for many more years to come. Cool white light - 4000K This CorePro LEDtube has a colour temperature of 4000K and 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, for instance.
