The lower price is not the better buy on the projector lamp – projector, office equipment – office supplies industry
In Projectors In the lifetime of the bulb to be replaced, then how to choose the right light bulb then? A user that the more benefits the more expensive, but some users think that bulb is higher, the price the more expensive the better. In fact, the correct choice must Projector Type of proceeding to consider the use of environmental factors, it easy to select purchase for their own use of the projector lamp. General projector bulb purchase
there still exist some vague understanding, mainly in the following aspects:
1, do not have to buy projector bulb manufacturers packaging. As we all know, the world's only manufacturer of projector bulbs PHILIPS (UHP), USHIO (UMPRD), OSRAM (VIPR), Panasonic (MSCR), EPSON (UHE), and so few, projector bulbs manufacturers of these manufacturers to more orders, and their own Stands and packaging production. The light bulb manufacturers produce only light bulbs, is not responsible for Lighthouse and packing boxes.
2, purchase of equipment to prevent the wick of the lamp. There are a lot of unscrupulous businessmen and the ignorance of buyers to sell the bulbs for the wick to reap huge profits must be careful identification. The so-called wick is installed installed on the old cup wick of unknown origin (mostly mainland China), its life is very short, light should not reach the standard.
3, please be careful to use non-original series produced by UHP lamp. This projector lamp is not the difference between appearance and original, looks very pretty. However, technical and technological reasons, after three months of this bulb brightness decay quickly, life expectancy shorter than the authentic manufacturers of light bulbs. The market a lot of unscrupulous traders to sell it as genuine in order to reap huge profits.
Non-factory original lamp bulb as a place:
1, bulb quality, easy to burst. Judging from its appearance, thin cup light bulbs, under high temperature and pressure are easily damaged. Although the system according to plant bulbs manufacturers warranty committed to six months, but for a normal bulb would have a direct impact on the work of learning.
2, bulb is not enough. Practice shows that due to technical and technological reasons, bulb should not meet standards. Estimated that only 70% of original light bulbs, and used for some time, the brightness decay quickly.
3, used for only half the original bulb. In accordance with the use of time to count, two non-original light bulb is equivalent to an original light bulb, bulb than the original purchase price of an expensive.
4, using the user understand the situation of bulbs, many unscrupulous businessmen sell it as genuine to genuine profits (profit of 5,000 yuan or more), especially dealer is responsible for changing light bulbs when the door must Ortega carefully. Now leave UHP lamp there are many, there is the mainland copy UHP, it's lights Cup appearance with the real goods are significantly different; there Osram company produced the UHP, appearance and Osram out VIPR bulb is similar, but the wick on have a filament around; there could have been UHP100W replaced with the 120W, 150W, 200W cup; also wick ass behind a filamentous conductive pole; there are hot do not know how long the life of the yellow cup. Really real Nanbian, unless you are a light bulb professionals. These false UHP lamp for low cost, low price with the user understand recognition in the market to sell at a low price, less and less original bulb has become increasingly difficult to sell.
