Whether you are playing games, watching movies at home or facilitating regular meetings you will be looking for a surface to project upon. This choice leaves you with a number of areas to consider, such as what product to choose, the cost and many many more. This article deals with just one of the areas you should consider when choosing a projection product; Light Reflective Value (LRV).
We will explain exactly what LRV is and what you should be looking for in a projection product.
What is Light Reflective Value?
LRV or Light Reflective Value is the universal term for contrast. It measures the proportion of useful light reflected by a coloured object. In terms of projection it is when a projector sends light at a wall the LRV is the amount of light that bounces back.
LRV is measured on a scale from 1 to 100, 0 represents perfect (absorbent) black which is 100% non-reflective and 100% represents perfect reflecting white. In reality 100% perfect white does not exist.
Can I choose ordinary paint to project onto?
When choosing a projection product, Light Reflective Value is an important factor to take into consideration. The higher the LRV is, the more light that will be reflected. The more light that is reflected, the better the quality of the projection. Traditionally, ordinary paints have an average level of LRV unlike specially designed projection products.
Light Reflective Value of Smarter Surfaces products :
- Smart Projector Paint has a LRV of between 90-95%
- Smart Wall Paint has a LRV of 90-95%
- Smart Dry Erase Wallcovering has a LRV of 90-95%
- Smart Blackboard Paint has a LRV of 0-2%
Smarter Surfaces products have a high Light Reflective Value. This excludes Smart Blackboard Paint, which the user would not want to reflect any light.
Why should I choose Smart Projector Paint over Whiteboard Paint?
While Smart Projector Paint and Smart Wall Paint have a similar amount of Light Reflective Value, Smart Wall Paint has a much higher gloss level. This means it does not project upon as clearly as Smart Projector Paint which has a high opacity to facilitate the projection of bright, sharp images in high definition. Smart Projector Paint can be used with 99% of all projection equipment.
Smarter Surfaces also offer a Smart 2-in-1 Wallcovering: Projector and Dry Erase which combines the two functionalities of dry erase and projector into one innovative product.
