Comparison of efficiency of KRAFT LED lamps and standard LED lamps

See a comparison between KRAFT LED lamps and standard LED panels on the market on a number of factors including efficiency, power, operational warranty and more.

Comparison of the efficiency of LED lamps through laboratory tests

The tests compare the performance of KRAFT LED lamps against traditional LED panels available on the market. The tests were performed by "Science and Information Center for Testing of Electric Lamps and Technological Ownership" and DP "Poltavastandartmetrology". Their results can be validated using the following laboratory analysis numbers: 10.1-5880 and 10.1-4766.

KRAFT LED
Standard LED panel
1. Rated power, W
Nominal power of the device. Calculation of total power, including active and reactive electricity, see point 8.
27,2
36,6
2. Amperage, A
The amperage is used to calculate the total power, including active and reactive electricity, see point 8
0,131
0,311

3. Power factor, cos φ
Active power is used for useful work. The closer the value cos φ is to 1, the better.

0.94
0.53

4. Light flux, Lm
The higher the luminous flux number, the more light you get from the lighting device.

2064

5. Luminous power, Lm/W
Luminous flux is the ratio of the light from the source to the power consumed by it. It is an indicator of efficiency and economy.

6. Color temperature, K
Three shades are usually distinguished: warm (≈2700-3000 K), neutral or white (≈4100 K) and cold (≈ 6500 K).

7101

7. Color rendering index, Ra
The higher the index, the more naturally lit the objects will be. Maximum Ra — 100 (sun). A Ra of 70 to 79 is fine. Ra from 80 to 89 — very good.

8. Full power with consideration of the power factor cos φ, VA
The total power of the lamp is calculated by the formula:
P = UI,
where P — total power (W), U — voltage (V), I — current (A). The test voltage was 220 V. The amperage is subtracted from point 2.

For KRAFT LED:
P = 220 × 0,131 = 28,82
For LED panel:
P = 220 × 0,311 = 68,4

28,82
68,4

9. Warranty, years
The warranty period of KRAFT LED is one and a half times longer.
