[Lesson In Lamps] Coverage Areas (Part 2 of 3)

[Lesson In Lamps] Coverage Areas (Part 2 of 3)

Picking a lamp is about getting the right intensity, in the right area. 

You're reading part 2 of a 3 part series

Here you'll learn how to get your coverage right.

Coverage areas

The exact area depends on the footprint of your reflector. But as a rough rule, to get your intensity right, here's how much space you should aim to cover with each lamp:

250W lamp 0.75m x 0.75m area
400W lamp 1m x 1m area
600W Lamp  1.2m x 1.2m area
750W Lamp  1.3m x 1.3m area
1000W Lamp  1.5m x 1.5m area

So, a 600W lamp, with a square reflector, in a BAY6 XL tent is spot on.

This doesn't mean you need a higher intensity lamp in a bigger tent, you just need to use multiples.

For instance, in a 1.2m x 2.4m tent, you know 2 x 600W lights would do it.

Don't forget, your exact coverage area depends on:

  • the shape of your reflector
  • the height of your reflector
