Which is better for Philips G12 metal halide lamp and NVC G12 metal halide lamp?

Of course, NVC's metal halide lamp is good, NVC started with metal halide light source, and has absolute advantages in home decoration and commercial light source, but the Philips brand is also okay, but there are too many fake and shoddy products!!

Philips metal halide lamp is good.

Fortunately, the light source of Philips' metal halide lamp is a ceramic bubble, ** around 100-110.

NVC's bubble, which is quartz, ** at 60-70

Things always pay for what you pay for!!

Philips' electrical boxes and light bodies are perfectly worked!!

The subject should refer to the metal halide lamps and lanterns used in clothing stores and stores, the upstairs is not complete, NVC is good, the original started with halogen low-voltage lamps, transformers, metal halide lamps and lanterns can not be talked about, domestic metal halide lamps and lanterns in the heavy use (lit 12 hours a day) environment, most of them are self-extinguishing, light decay, discoloration, completely broken problems, Philips lamps appear these problems are very few, I mean very little, the probability is low, if friends want to reduce the budget of lamps, When buying lamps and lanterns, you can choose domestic lamp shells, inductance transformers, Philips or Osram, GE lamps, the best but not low cost is Philips's electronic rectifiers, lamps, NVC lamp shells, about LED lamps and lanterns in recent years, but now in terms of color rendering, brightness, ** is still inferior to metal halide lamps, and metal halide lamps are also convenient to maintain, after all, the lamps and lanterns are mature in terms of standards, and it is convenient to buy accessories. LED I believe it will get better and better, if you want to buy it now, please choose the COB light source. **High, good brightness.

First, the application place.

Ceramic metal halide lamps are generally used in shopping malls, hotels, hotels, shops, clothing stores, optical stores and other places with high light requirements.

Second, the difference between quartz metal halide lamp and ceramic metal halide lamp.

Because the current technology in China can really produce ceramic metal halide lamp production malls, there are: NVC, Osram, Ningbo Nuotech and so on. Therefore, most of the metal halide lamps on the market are mainly quartz.

However, the quartz metal halide lamp cannot be compared with the ceramic metal halide lamp in terms of light effect, service life, and energy saving of Chatutan. The only drawback is that the current ceramic metal halide lamp is more expensive.

Third, if you want to buy ceramic metal halide lamp, it is recommended to recommend Ningbo Nuotaike in terms of cost performance, its price is the highest brand in the market.

I don't know much about the principle, but the general ceramic metal halide lamp will be much better in terms of color rendering. Ceramics don't seem to be expensive now.

That's the difference between the lamps ... Ceramic metal halide lamps have higher color rendering. The effect is more natural. **Naturally, it is not the same For example, the difference between the price of OSRAM's domestic G12 lamp and the imported OSRAM ceramic metal halide lamp is nearly three times.

It's the angle of the cup, and if you're going to look at a small area, choose a small angle, and if it's large, use a large angle.

Generally, the ** of foreign brands of ceramic metal halide lamps is generally high, and there are generally few domestic companies that can produce real ceramic metal halide lamps. If there is ** is also very expensive, generally the more cost-effective one is the ceramic metal halide lamp of Ningbo Nuotaike.

The Michelin card is good.

Adopt me, dear.

Foreign Philips, Osram. Domestic Yaming, Opple, Changzhou Langlang and so on.

The light flux of 250W ceramic metal halide is related to the specific manufacturer, which can generally be calculated according to the luminous effect of 80-100lm W, and 250 is 20000---25000lm. The high-power and high-pressure sodium lamp is generally high, and the 1000W high-pressure sodium lamp can be calculated according to the luminous efficiency of 120lm w, and the luminous flux is about 120000lm.

Please consult the light flux of 250W ceramic metal halide is about 25000lm, and the light flux of 1000W high-pressure sodium is about 150000. It varies from manufacturer to manufacturer.

The statement upstairs makes sense, because I have also actually tested it, and the ceramic metal halide lighting effect is almost 85lm w.

In the past two years, LED has been completely defeated, and in the early years, because of the lack of stability of high-power LEDs, the defective rate was relatively high.

Now whether it is the quality of life or the effect of energy saving, it is good for LEDs.
