The difference between LED Projectors, Laser Projectors and Light Projectors

Although not big, but the projector has its own users in Indonesia. Compared to wide-screen TVs, projectors are more flexible, easy and compact to carry around, and can even be used for various needs. Projectors can be used as productivity devices to support business, for education or education, as well as home entertainment devices. In the context of Eid 2022, Galaxy Star projectors can be a means of entertainment for watching movies with the extended family. Well, the challenge is to find the right projector for your needs. So, here are some things you should know before buying a projector.

LED Projectors, Laser Projectors and Lamp Projectors

There are many types of projectors. There are lamp projectors, laser projectors and LED projectors. Each has advantages and disadvantages, including differences in price, projection quality, and size. In general, projectors need a light source to project images. The Lamp Projector is the oldest type of projector. But also the cheapest, varied, with a mercury bulb and a relatively short service life. On the other hand, LED projectors and laser projectors come with more modern technology. Especially in terms of environmental friendliness and longer service life. Difference between Lamp Projector and Lamp-Free Projector

There are many things that need to be considered before choosing a Projector Lamp, or Laser and LED. Lamp age, price, and brightness level are important things to consider. Other considerations include color quality, power-up time, the appearance of rainbow lighting effects, and device noise. So, here are tips on choosing a projector:

1. Lifespan

Based on the specifications, the Lamp Projector, Laser Projector and LED Projector each have a lifespan of 10,000 hours, 20,000 hours and 30,000 hours. Equivalent to 14 months, 28 months, and 42 months for continuous use. This lifetime is related to length of use, not length of ownership. When using the LED Projector for 6 hours per day, the light source can last around 7,000 days, or 19.2 years.

2. The Projector’s Rainbow Light Effect is inseparable from problems. The biggest problem is the rainbow effect. Lamp Projectors and Laser Projectors use color filters, or color wheel glass, to adjust the light projection as needed. Therefore there are times when the light wheel glass is too slow, and the projected image displays unwanted colors, which is called the rainbow effect. Lamp Projectors and Laser Projectors have the possibility of causing rainbow light effects, while LED Projectors can minimize this effect.

  3. Brightness

Brightness levels are measured using lumens from the American National Standards Institute (ANSI). The higher the number, the brighter. The Lamp Projector has over 2,000 ANSI lumens. More than 3,500 Laser Projectors. In contrast, LED projectors only have a maximum of 2,000 ANSI lumens. However, LEDs are able to exceed numerical efficiency with higher image display quality.

4. Color Presentation LED Projector, Laser Projector, and Lamp Projector — all use the same color standard, Rec. 709. Although, the LED Projector is one step further with the ability to color saturation up to 125% of the normal number.

  5. Power-up time LED projectors and laser projectors, or lamp-free projectors, offer instant on/off capability. But not with the Lamp Projector, which needs a warm-up and cool-down time of around 2 minutes before and after use.
