I like and use high-tec LED flashlights for work, but something to remember about LEDs is:
...They don't put out full spectrum white (at least not the current LEDs, I'm sure they will in the near future). Incan does put out full spectrum, not sure about fluorescents. This is why you get sort of an undescribable "black and white" effect when using LEDs, even though you can see colors.
In a nutshell, it's a little harder to "see" with current LED lights because many of the colors that make up 'white light' are missing.
For example, I've read that police prefer lower-power incans over higher-power LEDs, because even at lower power, the incan will help them spot the perpetrator hiding in the dark, whereas the brighter LED may help disguise the perp because it's more difficult to see and recognize objects.
I gave a really nice, high-end ($50) LED headlamp (a
zebralight) to my electrician friend. He won't use it because he says that although it's fantastically lightweight, durable, and bright, he can't "see" with it.

PS: the issue about 'thrower' vs 'floody' worklights? A 'thrower' (focused beam) not the fault of the light source, but a fault of the design and the nature of the reflectors used. You can buy floody LED flashlights, such as the zebralight mentioned above. I don't know if anybody makes floody LED worklights, but they darn sure should. Can't think of anything more worthless than a "throwy" worklight!!
