Light Tip. Preventing power surge damage. How to turn the lights on.

Are you going to light a scene? Remember that when you turn the light on, the electric intensity goes up around 20% than the normal (i.e.: when light is normally on). For example, let's say you have 3 Tungsten lamps of 1000w each and the maximum power your installation can offer is 3300w. Which is fine because you only need 3000w in total: you still have enough watts to connect your PC and a battery charger.

But, if you add that 20% extra lights need to be turned on, you'll find yourself that you are exceeding the maximum power by 300w:

3 x 1000w = 3000w
20% of 3000w = 600w  
3000w + 600w = 3600w > 3300w

In order to protect your equipment (or the one you are renting) you should always turn the lights on one by one, leaving enough room for the light to get that 20% extra of energy needed.

Now that lights are on, start shooting!
