The most popular recently is LED. The full name in Chinese is 'Light Emitting Diode'. Low-power LEDs are generally used in multiple heads at 1AA or 3AA. It’s much worse. Let’s talk about the high power of more than 3W for outdoor use. The main representative is also the most popular LED in the United States. Parameters of main models:
(1) P3, 350mA brightness 73.9-80.6 Lumens, 700mA brightness 119.7-130.6 Lumens;
(2) P4, 350mA brightness 80.6-87.4 Lumens, 700mA brightness 130.6-141.6 Lumens;
(3) Q2, 350mA brightness 87.4-93.9 Lumens, 700mA brightness 141.6-152.1 Lumens;
(4) Q3, 350mA brightness 93.9-100.4 Lumens, 700mA brightness 152.1-162.6 Lumens;
(5) Q4, 350mA brightness 100.4-107Lumens, maximum current 1000mA;
(6) Q5, 350mA, brightness 107-114 Lumens, maximum current 1000mA (up to 220-250lm). Although there are many models, the most commonly used ones are P4, Q2 and Q5. The most popular one is Q5 because of its high efficiency and high brightness. The current can reach 1A, and the brightness can reach 250 lumens. LED color temperature: Each type of LED is also divided into different types according to the color temperature. For example, Q5 has Q5WB, Q5WC, etc., Q2 has Q2WB, Q2WC, Q25A, etc. Basically, the commonly used color temperature is from 5000-10000K. According to the K value, it is divided into WJ, WD, WC, WB, WA, etc. Generally speaking, the lower the color temperature, the more yellow, and the higher the color, the whiter.
