When you've made your IBL with the IBL generator isn't your new IBL's light intensity supposed to be 100-200%?

If you use Gen-IBL to make it, it will hold the exact amount of RGB that it got from sampling your environment. Which means if you want to match the environment, you should be using 100%. If you were using the trick I showed where you scale the incoming data by half, in order to compress it to fit more dynamic range into the LDR image, then you use 200% to match. (Twice a half is the original amount, but more fits in 8 bits.)

However, for artistic reasons, where you're just using an IBL as a controllable light distribution, it is perfectly valid to use any intensity you want to get the effect you want.

Only when precisely matching a sampled world do you have to use it at a specific intensity.

Of course, if you're having sloppy issues with shaders, particularly if they are not all perfectly balanced, you may feel the need to hack your lights.
