Switch from v150 to v156 everything went dark!

When I switched versions from 150 to 156. I find myself having to change lighting intensity from 1 to 3. Am I missing a key setting?

The intensities for ambient, hemisphere, directional lights and light maps can be restored by multiplying PI with the existing light intensity values.

Updates to lighting in three.js r155

The upcoming release r155 will contain a major change in context of lighting. The legacy lighting mode will be disabled by default which affects all light intensities and how point and spot lights decay. What does that mean for me? The release changes the default of WebGLRenderer.useLegacyLights from true to false and also deprecates the property. Meaning it will be eventually removed from the engine with r165. Setting WebGLRenderer.useLegacyLights to false is one important prerequisite for a…

Because r155 has been updated~

Actually for point and spot lights the intensity unit is now standardized (candela).

Thanks for your advice.
