After trying this daylight equivalent I am extremely impressed with its efficiency and brightness. The Industrial and Scientific application of this product is perfect for illuminating our warehouse.The long lifespan of 15000 hours is a definite pro, as we won't have to replace them anytime soon. However, they may not be suitable for areas that require warmer tones of light. Overall, I would highly recommend these dimmable lights for their energy-saving and durability..
