What is the brightness and wattage of LED tubes?

Most consumers in the purchase of LED tubes , the most obsolete way to buy 40 light, 60 light incandescent lamps. The brighter the light, the higher the wattage. The arrival of the LED lighting era will change the traditional method of selecting lamps, then how to choose the brightness and wattage of LED tubes ?

First, ask a simple question, a 7W LED tube, and an 8W LED tube. Which one do you think is brighter?

The answer is: not necessarily.

In fact, the light and darkness of light is measured by a professional parameter called lumen (lm), which is the main specification for measuring the brightness and darkness of a lamp.

Compared to 7W or 8W LEDs, they should look at their lumen output.

Because LED skills and incandescent lamp skills are different, the skills of incandescent lamps have been thoroughly matured and stabilized after hundreds of years of experience, and LEDs are constantly evolving and changing, and can achieve different functions through different combinations.

Therefore, it is also possible that the 7W lumen output is 8W higher, then the 7W lamp is actually more energy efficient than the 8W. Of course, because most consumers are relatively unfamiliar with the terminology of lm,

Comparison of brightness and energy saving between LED lamps and traditional lamps:

1W LED=3W CFL (energy saving lamp)

3W LED=8W CFL (energy saving lamp)

4W LED=11W CFL (energy saving lamp)

8W LED=15W CFL (energy saving lamp)

12W LED=20W CFL (energy saving lamp)

18W LED=40w CFL (energy saving lamp)

The original office used a 40-watt fluorescent tube, choose how many watts of LED T8 tube? At the same brightness, you choose 18W LED T8 tube, and save 50%! If your office uses the tradition Fluorescent tubes, you want to switch to LED energy-saving lamps, about the energy-saving retrofits that can be viewed in office lighting.
