Analysis of LED test reports and KRAFT LED profile

Rated power of the appliance. Rated power of the appliance. Calculation of total power including active and reactive electricity, see clause 8. 

Amperage is used to calculate full power including active and reactive electricity, see clause 8

Active power is spent on useful work. Jet electricity is a part of full power that is not spent on useful work. The closer the magnitude cos φ to 1, the better.

The higher light flux number the more light you get from lighting device. 

Light output is the ratio of the light emitted by the light source to the power consumed by it. It is an indicator of efficiency and economy of light sources.

The color temperature is responsible for the shade of light. Normally three shades are distinguished: warm (≈2700-3000 K), neutral or white (≈4100 K) and cold (≈ 6500 K).

The higher Ra index, the more natural will look lighted objects. Maximum Ra — 100 (sun). Ra from 70 to 79 is good. Ra from 80 to 89 — very good.

The total power of the lamp is calculated by the formula:
P = UI,
where Р — total power (Вт), U — voltage (В), I — current strength (A). The voltage at test was 220 V. The current strength is subtracted from item 2. For KRAFT LED:
P = 220 × 0,131 = 28,82
For the LED panel:
P = 220 × 0,311 = 68,4

The warranty period for KRAFT LED is one and a half times longer.

The total light flow of 100 KRAFT LED profiles is:
2812 × 100 = 281 200 Lm
Since the light flux of LED panels is 2064 Lm, then to provide the same level of illumination you will need:
281 200÷ 2064 = 136 pcs.

Retail price of LED panel is 699 UAH. Retails price of KRAFT LED kit is 1390 UAH. Then we get following expenses:
100 pcs. × 1390 UAH = 139 000 UAH
136 pcs. × 699 UAH = 95 064 UAH

Estimated cost of LED-panel installation - 200 UAH, KRAFT Led kit - 50 UAH:
136 pcs. × 200 UAH = 27 200 UAH
100 pcs. × 50 UAH = 5000 UAH

The difference in cost is about 16%

We take the average lighting time — 12 hours a day.
For profiles KRAFT LED:
27,2 W × 100 pcs. × 12 h = 32 640 W
For LED panels:
68.4 W × 136 pcs. × 12 h = 105 754 W

365 days a year

We calculate the cost based on the tariff of 3,61 UAH/kWh

Based on the analysis of test reports, the KRAFT Led lighting system is superior in quality. And according to calculations, it pays for its cost in 1-2 years of use due to energy savings.
