Overview of LED lamps Spectrum Led GU10 from Europe
We are testing LED lamps with a GU10 base for 6 and 10 watts. Samples were provided by the official distributor of the Spectrum LED trademark in Russia, LLC TSC Teplomarket. Bulbs imported from Europe.Characteristics
Spectrum LED
lamps with GU10 base are in the mid-price range. Retail price: 6 W - 78 rubles, 10 W - 164 rubles, in connection with the start of sales, the price was reduced by 30% to 60 and 126 rubles.
Indirectly, the service life can be judged by the warranty period, for bad bulbs it will be 1 year. The Polish brand Spectrum LED provides a 2-year warranty period for its lamps, during which you can exchange for a new one.These bulbs can be screwed into a standard E27 base with an adapter.
About Brand
In 2019, LED bulbs of the Spectrum LED trademark, which belongs to the Polish company Wojnarowscy, first appeared in Russia. The company started in 1990 as a supplier of lighting equipment for factories, railways, mines and medical institutions. The products undergo a two-stage quality control, the first stage is carried out by the company's specialists at the manufacturing plants, and each batch is re-checked in its own laboratory in Poland.Equipment
List of used devices:- thermal imager: Seek Thermal Compact PRO
- Photometric Scope: SpectraLight DIY-05
- power meter: Robiton PM-3M
- spectrometer: UPRtek MK350
- Light meter: Radex Lupin
All devices are tested and configured in certified lighting and electrical laboratories.
Energy consumption
We measure power using a wattmeter and an adapter from the GU10 cap to E27. Actual power consumption turned out to be lower than declared by 9% for 6 W and 5% for 10 W, which means we will pay less for electricity than expected.
Light flow
Before measuring the luminous flux, we warm up the GU10 LED lamps for 60 minutes. During this time, the lamps reach a stable mode of operation.The results of measurements in the photometric sphere show that the real luminous flux was much higher than the declared one: by 31% for a 6-watt bulb and 23% for a 10-watt bulb.Heat
To measure the temperature of the housing and LEDs, the samples are heated with a diffuser. Immediately before the measurement, the diffuser is removed and measurements are taken.
Modern LEDs used in general-purpose lamps, according to the specification, can heat up to an average of 120-125 degrees without loss of declared characteristics. If the temperature of the LEDs is below 100 °, then this is a good indicator.The LEDs of the Spectrum LED bulbs during testing showed a temperature of 83 and 86 degrees, that is, they work in a comfortable temperature range, which means we can expect a long service life.Color rendering and light temperature
The specifications indicate a color rendering index Ra> 80 units. According to the test results, 80.9 and 81.3 were obtained - the lamps are suitable for installation in residential premises, since according to the regulations for residential premises, the color rendering should be at least 80 units.The color temperature of GU10 LED bulbs is 3000K, which corresponds to warm white light.
Packaging
The packaging is made of glossy cardboard, pictograms and generally accepted signs are used to indicate characteristics, explanations are provided in all European languages.
Summary
Test results showed:- energy consumption is lower than declared by 5% and 9%;
- luminous flux higher by 23% and 31%, which is rare;
- color rendering coefficient corresponds to the declared;
- the temperature of the LEDs does not exceed the recommended 100 ° C, which greatly increases the service life.
Where can I buy?
You can buy Spectrum LED lamps with GU10 base in Yandex Market and in the online store of the official distributor of TSC Teplomarket LLC, which provided samples.Link to GU10 6W and GU10 10W .
