If you think the Inova T4 is amazing...
I've done a side by side comparison of the Pelican 7060 and LumaPower MRV and the LumaPower is unquestionably brighter but it was closer than I expected.
There are plenty of production LED lights brighter than a T4 - though adjustable focus is a very rare feature and really isn't necessary on a well designed LED light.
The output winner for a production flashlight as of today has to be the Tiablo A9 with 256L at the emitter.

Actually, let me qualify that - you can get a Foxfury 9 cree etc for like $999.
The LumaPower MRV and Tiablo A8 also bear looking at.
I personally own an Inova T4 - 2 of them actually - and still like them very much as high quality, rechargeable, 'around the house' lights.
