How to judge the quality of LED flashlight bulb
I am doing titanium lighting flashlight, the flashlight irradiation effect is relatively strong, mainly focusing flashlight with 800 lumens from single chip CREE XML T6 LED, close the pan light intensity, long distance focusing, pavement irradiation effect is great, and the first choice is the outdoor riding at night. 18650 hours straight, with another T6 LED small size, brightness super awesome, you can exchange.
The flashlight lamp is good or bad, ordinary people can be used to distinguish the brand. The United States is the most common flashlight on the CREE lamp, as long as the formal channels of products generally are of good quality, common models are Q5, R5, XML T6, MCE etc..
If there is no brand LED, there is no professional instrument, you can from the LED packaging process (fine or rough), as well as after the light color, consistency and purity and so on. LED is not very good color, the same batch consistency is not good, LED is not good.
