The COB power is determined by the number of power watts used, and the COB itself is a common wattage. Scope of application: downlights, spotlights, ceiling lights, track lights.

Note: Do not use full power when using. Because high-power LDE generates a lot of heat, it is necessary to add a heat sink. It is definitely not enough to rely on the heat dissipation of the substrate itself. If the heat dissipation measures are not done well, COB is prone to light decay, burns, etc. At the same time, in order to ensure long-term use of LED COB, it is recommended to use a constant current driver board, and apply silicone grease to the bottom of the COB substrate.

  • Super high beam. Small enough to put in purse or deep pocket but with very strong beam. Long lasting batteries. My grandson loved it so much, he wanted another one to have one in car and one in house!

  • The flashlight is very bright compared to ones I've bought in stores and for half the price. I love that it's rechargeable and comes with different cords depending on your charging preferences.

  • So far, this thing is BRIGHT. I'm talking, able-to-see-it-on-a-sunny-day bright. It was also a pleasant surprise to see that it came with a spare battery. I'm taking it camping this weekend, so if I have any problems with it, I will update.
