What kind of light would set off explosives

-A simple magnifying glass will ignite wood on a sunny day so it is not exactly the type of light but more the intensity.Certainly anything that could create a spark (which is tough for light).Otherwise, it would have to be intense enough to heat the gas to a high enough temperature that it ignites.......
Yep basically what type of light source would be the most dangerous near explosive gas?

I'm interpreting this question as what type of light would be dangerous in the presence of a combustible gas and not gasoline in liquid form, and that this gas is not contained within a cylinder or a tank. I'll assume the gas is in a free state, in an enclosed room with windows or a container with a glass aperture.
So the light would have to be of a concentration or energy that would ignite a gas in an enclosed room.
A focused beam such as that from optical lenses and sunlight, or from a laser , would have the energy to initiate a combustion by ionizing the gas at the focal point, under the right conditions.

If this is a safety question for storing gas cylinders, they should always be stored in a cool dry place, and out of direct sunlight.
