I decided to upload a video to show what the KTC slim LED light is like:

This cordless LED light emits a soft white light that's very uniform in colour temperature and casts the light with a very wide angle, without any unwanted rings/halos. There are no hues of purple or blue light that you typically see on cheaper LED lights. Therefore, it's ideal in areas where proper colour rendition is needed, like under the dash, working with different colours of wires.
It has two output settings to suit different lighting needs and the slim profile gets into tight spots other lights simply can't fit into.
[update] Here's a comparison shot with a Skinny Light (MAC Tools version (Matco also sells them). It has more 12 LED's instead of 8 on the KTC. It has three settings for light intensity. At [high], it's brighter than the KTC, but throws a more commonly seen bluish hue, and because it has a transparent PC lens, the illumination has more glare and the light is less natural looking. The KTC has a frosted lens which helps to cut the glare, creating a soft, natural looking light.
The angle of illumination is equal on both (around 160 total degrees).
Recharge time is the same (2 hours)
Run time is the same at [high] setting (2 hours, IIRC)
Both will run at 100% output all the way until it ultimately shuts down (unit will alert low charge)
LED manufacturer: Skinny Light = Nichia (Japan) / KTC = Nichia as well??
COO as listed on package: KTC = China / Skinny Light = Malaysia
Construction/design:
KTC has a round handle; Skinny Light is flat throughout -- both has its pros and cons.
Skinny Light is constructed more ruggedly and the composite body allows for the unit to bend to a degree.
KTC has a better overall finish, IMO, but seems more fragile from flex.
Skinny Light is water resistant; KTC isn't.
