As someone who does this for a living, you almost can't have too many lights...
For prolonged under the hood work, or dash/interior work, the style of light we most often turn to is a spring loaded bar that grabs the body as a hanging bar, and your work light clips onto a carriage/holder on that Bar, in turn you pivot the light as needed, or grab the release tabs and move the light side to side as also needed. I have that Festool Light and the stand, I think the lighting pattern would be your biggest regret , followed by the base being in the way as noted by onocoffee. But try it, might work for you.
But for all other work, under the hood as noted, the Braun style work light is smaller, gets into tighter spaces than a big hanging assembly, and is closer to something you need to really shine a light on. And they're cheap, esp if you manage a discount coupon for purchase.
They have a spot light on the end that you can switch to, or not, like other style work lights of this type have. And the Main 'bar' light has two lumen settings, so it's adjustable to save battery life if needed while on a job.
I have a Braun at home that I'll still use for that purpose , but at work I've switched to a version made by Snap-On. Folding style, so it's more compact than the older Brauns/Harbor Freight lights were. Not round , so it doesn't want to constantly roll if you can't secure it with the magnetic base for a given task. Lights of this type are slim enough that you can actually fit them inside a door of a vehicle , in case you need to see latches or cables or something once you've got the Door Panel Off.
The other problem I had with the Brauns was just that as a day to day light, we'd wear them out. The upper section would break off from the lower battery section- sometimes the battery would just go bad and no longer take a charge. Occasional users aren't going to run into this, so it's mainly a Pro Shop/usage issue admittedly.
Here's a link to the Bar Style Underhood lights that I'm talking about. This is the straight light bar, my style is that the light is a POD, and is moveable across the length of the bar, which I prefer since I might need the most Lumens in one area, and not the whole engine. I also prefer corded vs rechargeable, I've seen people lose the light when they least needed to.
