Review: Good quality - Excellent quality, gives bright, even light. Review: Perfect Match and Great Quality LED Tape Light - I purchased this LED tape light to replace a failed section of an existing setup, hoping it would be a close match—and it was perfect. Installation was a breeze, thanks to the strong adhesive backing, and when connected to my existing driver, it performed exactly as described. The LEDs are small, densely packed, and provide a bright, uniform light output. Just be mindful of power requirements—a 2m strip worked well with my 12V/1A driver, but a full 5m length would need a 3A driver. Overall, I’m delighted with this product and highly recommend it! ## Features - 【Narrow PCB 5mm Width】The width of this COB light strip is only 5mm, while the width of ordinary COB light strip is 8mm.Compared with the general 8mm COB strip,the narrower 5mm allows you to install more easily,suitable for narrow spaces. - 【Cuttable】The strip can be cut once every 1cm/0.39in, the accuracy is higher than the ordinary strip, the cutting point of the strip is on the back of the plate, you need to tear off the double sided tape to see. - 【Uniform light emission】 The COB technology enables a much higher packing density of the LED array, No dark spots, Higher luminous efficacy.
