It is a measurement of the protection an item will have against solid objects (dust, sand, dirt, etc.) and liquids.
An IP rating is comprised of 2 numbers, both of which give you information about the protection level. A higher number means greater protection.
The first number (0-6) refers to the level of protection against solid objects and moving parts, such as dust, debris, or other solid matter.
The second number (0-8) references the level of liquid and moisture protection.
Here are a few examples:
- IP65 = Water resistant. “Protected against water jets from any angle” *Do NOT submerge IP65 LED lights, these are not waterproof.
- IP67 = Water resistant plus. “Protected against the events of temporary submersion (10 minutes)” *Do NOT submerge IP67 LED lights for extended periods, these are not waterproof.
- IP68 = Waterproof “Protected against the events of permanent submersion up to 3 meters”
Low IP ratings are appropriate for:
Protected use inside sealed products
Inside sealed signage
When using aluminum extrusions
High IP ratings are appropriate for:
Unsealed outdoor locations
Places that have a lot of debris
Areas with heavy foot traffic
High splash areas
High contact areas (people touching them)
What beam angle should you choose for your next project? We want to help in your decision-making process for selecting the right beam angle for your project.
First, and most importantly, if you install lights at a certain height, how much light will be on the surface area of your floor? Follow this equation:
BEAM WIDTH = ANGLE x .018 x DISTANCE
Technically in lighting, the beam angle is considered the points on both sides of the light spread where the intensity drops in half. Say you have a 40° light bulb. At 20° on either side of that central point, the light intensity is ½ the intensity right under the bulb. 20° + 20° = 40°
After 40°, some light continues even outside of this range. The light output of a lamp does not stop exactly at both ends. Some light shines even outside of this range, but beam angle is determined where intensity or brightness of the lamp drop in half from the center point.
