Just posted a review of the Hexolux D7 light, which is a versatile LED light that creates a nice-looking beam with good color accuracy, power and control. The D7 isn't cheap at $2400, but no next-gen LED is these days. The good news is that lights don't get outdated nearly as quickly as cameras do. You can take the financial hit upfront, and then get good use out of the light for a decade or more.
