Chip de lâmpada LED branco/branco quente de alta luminosidade 10W 900LM DC 9-12V

1

LGisMe Escreveu 3218 dias atrás. Using a coffee can for a holder and heat sink. Lamp begins to illuminate at 7v and if bright and not hot at 9v. Above 9v the lamp gets increasingly HOT and will become too hot to touch. I am using a buck converter to drop the voltage from a 3s lithium polymer battery (LiPo). The coffee can is wrapped with a 5m LED strip for a lantern effect and the 10W LED lamp on the bottom for a flashlight. Works great. You can also use an inline LED strip dimmer for the strip and the lamp. Great for camping and emergency lighting.

Para foksa 11/01/2018 I was skeptical at first considering how cheap this light are, but they are great. Light is really bright. They do generate a decent amount of heat when running at full power but that is normal for this kind of LEDs. To use them to their full potential you will need a current limiting driver ( http://bit.ly/2vV29RT ) and a decent heatsink: http://bit.ly/2vUJPs7
