Introduction
If you’ve ever wondered how the underwater scenes in movies or aquariums are brought to life, you’ll be interested in reading this article about underwater projectors. While above-water projectors are more commonly used, underwater projectors have gained popularity, especially in aquariums and pools. In this article, we’ll compare both these types of projectors, with a focus on the advantages and disadvantages of each. So, let's dive in!
Above-water Projectors
Above-water projectors are a popular choice for home theaters, outdoor cinemas, and conference rooms. These projectors use either DLP or LCD technology to project an image on a screen or a surface. Their brightness is measured in ANSI lumens, with higher numbers generally equating to brighter and clearer images.
Advantages
- Above-water projectors are typically less expensive than underwater projectors with similar specifications.
- They have higher lumens ratings than underwater projectors, generally ranging from 1000 to 5000 lumens.
- Although not designed for underwater use, some above-water projectors can be used near water, making them versatile for both indoor and outdoor use.
Disadvantages
- Above-water projectors are not waterproof and can get damaged if exposed to water or moisture.
- Their image quality can be significantly affected by ambient light, and a good viewing experience requires a moderately dark or dimly-lit environment.
Underwater Projectors
Underwater projectors, as the name suggests, are specifically designed to function underwater. They use the same technology as above-water projectors, but with modifications to make them waterproof and suitable for use in pools or aquariums.
Advantages
- They are waterproof and can be submerged in water without any damage or adverse effects on the projector's lifespan.
- They can produce crystal-clear and vivid images when used in water, creating an immersive underwater ambiance for swimmers or spectators.
- They have high contrast ratios compared to above-water projectors, which is essential for creating ideal lighting conditions when used in water.
Disadvantages
- They are considerably more expensive than above-water projectors, generally ranging from $2500 to $5000.
- Their lumens ratings can be significantly lower than above-water projectors, usually ranging from 200 to 1200 lumens.
Conclusion
Choosing between above-water and underwater projectors ultimately comes down to your specific needs and budget. If you’re looking for a projector for indoor or outdoor use, and you plan on using it close to water but not necessarily in it, then an above-water projector is a great choice. On the other hand, if you’re looking for a projector that can produce stunning underwater visuals, then an underwater projector is the better choice. Either way, both of these types of projectors have their own unique advantages and disadvantages.
