The total sample of 20 batches, the test a total of six batches failed, the failure rate of 30%. found that the main problems for the lamp power, initial luminous efficiency, color characteristics, dimensions, marking. Of these, five batches "light power " project failed, involving European Airlines, Horizon, chasing sticks, Li Bite, the power sub-brands.
It is understood that the power failure lights, is the actual lamp power and the nominal lamp power deviation exceeds the deviation range. This effect has two aspects: First, the measured power if the lamp is small, then the brightness of lights will be greatly reduced; Second, if the measured light power is too large to no energy.
Reminded
Consumers to buy energy-saving lamps should be noted:
First, look at the packaging of goods without name and address, trademark, rated current, rated power and other signs.
Second, pay attention to the site for a light, the site should hold the lamp housing, rather than a hand to hold the tube directly to the site, and then check the appearance of light in the lamp housing shall be clearly marked on the light source of sign Rated voltage and voltage range, rated power, rated frequency; check the lamp bulb is bright and clean no bubbles, no phosphor coating is fine particles; hand shaking the whole ring lights should not have.
Third, the requirements of test lights. Quality product has the comfort of light emitted, if the look will feel stimulated, issued unqualified cast a light like a gray, light on the object color distortion.
