☕️ 📉 👵🏿 TL-SREET 55 5K LED Street Light Review 💆🏻 🐾 🕵🏾

The review involved a street LED lamp TL-STREET 55 5K LC F3 D, provided by the company Glavsvet http://www.glavsvet.su , which is engaged in the supply of various lighting equipment. We use a thermal imager, a wattmeter, a spectrometer, a photometric sphere, a light meter.

Specimen characteristics

The table shows the parameters declared by the manufacturer and the results of measurements taken in the laboratory. The sample uses energy-efficient OSRAM DURIS S5 LEDs. It is completed with console fastening.

Parameter	Claimed	Measured
Power	55W	51W

Light flow

The measurement of light flow is also carried out after preliminary heating. During this period of time, the luminous flux stabilizes. The TL-STREET 55 outdoor LED luminaire is made using efficient 5000K Osram Duris S5 LEDs. Efficiency is from 140 to 170 lumens per 1 watt at a crystal temperature of 25 degrees. In this sample, after heating, the light flux decreases by 5-6%, which corresponds to the value stated in the documentation.

	Claimed	Measured
Light flow	6893lm	6640lm
Ripple	<1%	<1%

According to the test results, the deviation was 3% of the declared with an acceptable ± 5%, this is an excellent result. It is necessary to take into account the error of the measuring instruments; when measuring the luminous flux, the error of the instruments is permissible up to 15%.

Heat

Due to the large area of the cooling system, the LED crystals are heated to 63 °. According to the documentation of Osram Duris S5 LEDs, crystal heating is permissible up to 125 degrees while maintaining the declared characteristics.

-	Degrees
LEDs	63 °
Housing	54 °

On methods of measuring the heating of LEDs, consultations were held with a representative of the world famous company CREE. They also sent samples to compare with Chinese fakes.

Spectrum and color temperature

According to the test results, the color temperature is 5000K, the color rendering index is 71 CRI. Low color rendering significantly reduces the cost of the LED, so it is used only for street lighting.

Power supply driver

This model works at a voltage of 90 volts without reducing the level of luminous flux of the street lamp. Measurements were taken using a laboratory power supply.

Where can I buy?

Summary

This sample has a good ratio of price and quality. Due to the low heating of the LEDs, the service life will be maximum, up to 100,000 hours. After this period of time, it will not go out, only the brightness will decrease to 70% of the original according to the international standard LM70.
