There are thousands of LED tube lights in the lighting market, made by various manufacturers and featured of different specifications, prices, and applications. When buying LED tube light, what we should take into consideration? An insider gives us a list of six points you should know.
1. Luminous efficiency
Generally speaking, the fluorescent lights we use in our daily life has a luminous efficiency ranges from 55 lm/w to 80 lm/w. However, luminous efficiency of LED light reaches over 100lm/w. Buy LED tube light with a high luminous efficiency is your first choice.
2. Lighting angle
Most of LED tube light emits light at 120 degrees around its self, all of which is effective light. It can be adjusted according to your specific needs. Before buying LED tube light, we need have a clear realization of the lighting angle we need in order to get our ideal lighting effect.
3. Work Efficiency of Power
Work efficiency of power has a impact on the whole light efficiency since all lights expect incandescent light lamp are supplied by specific power.
The outstanding feature of LED tube light is indubitable long rated life. That’s why many consumers replace conventional light of LED tube light. Lifetime of a good quality LED tube light reaches up to over 50,000 hours. The long lifetime reflects its great raw material and high technology, and vice versa.
5. Color Temperature Rang
The wider color temperature ranges, the greater adjustability it has. LED tube light having a wide color temperature rang can be largely adjusted to meet your individual needs.
6. Color Rendering Index (CRI)
Color rendering index of conventional LED tube light is more than 80. The one of incandescent light is 95. The higher color rendering index is, the superior light it emits.
