WebGl : lights does not working well


I have 1 directional Light and 3 spot Light in my scene. No baking.
Quality is set to good and pixel Light Count is 50.

I have try “forward” and “deferred”, render mode of lights to “important” but always the same result.

Look lights on the wall.

In Unity standalone :

In WebGL :

In WebGl lights intensity is near 0 and I dont understand why.

Thx for your help.

Do u solved it? I’m having the same problem!
