Currently on the market , LED products of varying quality , the price is very confusing, even for the same product , the level of the price difference between King ran up to 10 times. 5 -watt bulb for example , expensive to hundreds of dollars , as long as a few dollars cheaper , the price difference is so great that consumers are kept, even no choice.
The following will give you a detailed analysis of these two products. Where high-end products for ENELTEC of 5WLED bulb, hereinafter referred to as "ENELTEC", the low-end products for a certain brand of Zhongshan , priced at $ 6, hereinafter referred to as " a certain brand ."
The appearance, product design aesthetics ENELTEC , feel heavy, metal shell , with good heat dissipation, ensuring long life of the LED. The appearance of a certain brand of rough , feel very light , plastic shell , no heat capacity , can not guarantee a long life of the LED.
Turn on the lights , ENELTEC light bulb would have a better quality , it feels very comfortable light , and no flicker . A certain brand of light bulb impure , mainly CRI is not high , and there is a serious flicker, likely to cause eye fatigue.
Open shade look , ENELTEC using glass shade , soft light, not easy to aging , LED COB ceramic devices , light is better, the entire COB placed on a metal heat sink , the assembly process is extremely fine .
A brand is using ordinary 2835 lamp beads ( of course not to say that 2835 is not good here , but its use is low in 2835 , bad glow ) , glow general , PCB board as a normal FR4 board, poor thermal performance and no metal heat sink , no heat capacity , PCB enclosure by four small card bit stuck , assembly process in general.
ENELTEC bulb switch power supply is isolated constant current source , a capacitor for avoiding thermal design to improve the power of life , while inside a plastic body for electrical isolation , with high security.
Using a certain brand of low-end power RC Buck , poor performance , poor stability , short life .
Different brands of LED lights visible , either in quality or price difference is relatively large , and from the perspective of quality and safety , we recommend that consumers buy a certain well-known brands of plant products, the quality is guaranteed .
