How to identify the advantages and disadvantages of energy-saving lamps

Energy-saving lamps have been increasingly welcomed by consumers due to their features of significant power saving, long service life, no stroboscopic effect, no noise, and a wide range of soft light operating voltages. There are many energy-saving lamps on the market today, and the quality is uneven. How to buy your own satisfied products in the array of energy-saving lamps in the lighting store? Through "seven look" can identify the advantages and disadvantages of energy-saving lamps, as described below.

A look at packaging and trademarks

The state mandates that energy-saving lamp products be marked on the packaging with the following contents: source mark, rated voltage, voltage range, rated power, and rated frequency. On the lamp, on the packaging, or on the instruction manual, note the lamp current, and other supplementary instructions relating to safe use. Generally speaking, the trademark of high-quality products is of good quality and printed with clear characters and is not easy to fall off. Wipe with soft and damp cloth, the mark is clearly legible, it is not easy to wipe off, and there are manufacturers' trademarks and related certification marks. Fake and shoddy products have poor print quality, fuzzy fonts, and are easily erased. There are no manufacturer's trademarks and related certification marks.

Second look at the quality of plastic parts
The plastic shell of energy-saving lamps must be made of flame-retardant engineering plastics. The advantages are: heat-resistant flame-retardant, good electrical insulation, high hardness, good rigidity, resistance to cracking, easy printing, and white discoloration. The disadvantage is that the cost is a bit expensive. Ordinary plastics are prohibited from being used in the production of energy-saving lamps. The inferior and inferior products use medium and low grade plastics, whose heat resistance, flame retardancy, etc. do not meet the requirements of the standard. They are brittle, easily cracked, and easily discolored, causing hidden safety problems.

Three to see the appearance of the lamp

When comparing multiple lamps together, the consistency of the shape and size of the lamp is much larger and the quality is guaranteed. At the same time the shell can not have cracks, loose, seals should not have been smashed marks, in the installation, removal process, the lamp should not be loose, boring head phenomenon.

Four look fluorescent tubes

High-quality products use rare earth trichromatic phosphor coating, which has high luminous efficiency, high color rendering index, good thermal stability, resistance to 185nm UV-induced light decay, and long life. A high-quality energy-saving lamp is equivalent to the use of 3 to 8 low-quality energy-saving lamps, but the price is high. Fake and inferior products use halogen powder or rare-earth tricolor fluorescent powder mixed with halogen powder mixed powder coating, its luminous efficiency is 30% lower than rare-earth trichromatic phosphors, low color rendering index, poor thermal stability, light degradation, short life, especially Not suitable for use in thin tube fluorescent lamps. The methods of identification are as follows: 1. The light illuminates the palm of the hand: Let the light of the energy-saving lamp shine on the palm of the hand. If the palm of the hand is ruddy and bloody, it is a three-color energy-saving lamp; if it appears green, no blood, it is halogen powder energy-saving lamp. 2. Look at the lighting time method: if it is lighted for a few minutes, it can reach normal brightness, bright and soft, and it is a three-color energy-saving lamp; if it is energized, the brightness will reach the peak value, the brightness is low, and the light color is blue. Pale and weak, it is a halogen powder lamp.

Five look at the quality of electronic ballasts

High-quality products are manufactured through reasonable circuit design and selected high-quality electronic components. They have small heat generation, high power factor, and are equipped with filter parts. The harmonic content is low, and there is basically no electromagnetic interference to the power equipment. The designed operating frequency is high. Achieve the level of no-frequency flash source, protect the eyesight and physical health of consumers. In order to save production costs, counterfeit and inferior products can be assembled and produced by outsourcing low-quality electronic ballasts. The quality cannot be guaranteed, and the failure rate is high, which may cause serious fire safety problems.

Six to see the temperature at work
Energy-saving lamps under normal operating conditions, the temperature rise should be very low. Otherwise, the life span of the energy saving lamp is very short. At the same time, when the energy-saving lamp is lit, both ends of the lamp are black and the filament is red or shiny, which all indicate that the energy-saving lamp has a quality problem.

Seven look start performance

If there is a regulator during purchase, first adjust the voltage regulator to 150V or adjust to the minimum starting voltage value in the instruction manual in the de-energized state, install a naturally placed energy-saving lamp, keep the hand and body away from the lamp, and turn it on. It is best to light the power once. Because the energy-saving lamp starts has two characteristics: First, the higher the temperature is easier to start; second, it is easy to start in the case of human body induction. In addition, it is worth mentioning that many energy-saving lamps are on and off, which is detrimental to the life of the lamp. The energy-saving lamp should have a preheating circuit in the interior of the lamp, with a delay time of about 0.4 seconds.
