The reporter saw in the lighting market that a 4 watt Philips MASTER LED bulb was priced at 60 yuan, while some unknown brands only cost 10 yuan, and even LED lamps sold for as low as 5 yuan. The price is confusing.
Since the current quality certification mark for LED lamps is not available, experts recommend choosing brand products as much as possible. Domestic and foreign brands such as Philips, Osram, and Hongyan have done a good job. Big brands out of brand benefits will not harm the brand image for small profits.
When users buy lights, they only look at the brightness. Industry experts say that LED lights are not as bright as possible. "The color temperature of the lamp will be marked. The higher the color temperature, the higher the light effect and the brighter the color. In fact, the low color temperature looks more comfortable and the cost is higher." Insiders explained that the color temperature of the morning and evening sun is 3000K~3500K, softer, rising to 4000K~4500K at noon, while the color temperature of incandescent and fluorescent lamps is around 6200K.
It is reported that the general household LED lights are 3~7 watts, and the domestic light source (only refers to LED granules) is priced at 2~3 yuan/watt, so the price of 4 watts is about 20~50 yuan, if it is lower than 20 yuan. There is a problem with quality. Subsequent maintenance is also a big problem for LED lights. In this respect, it is clear that brand companies are more trustworthy.
