Are your subjects people or things?
If you are photographing things, your task becomes easier.
People are harder because you can't just lock everything down and take long exposures. LEDs put out a lot less light than strobes for still images. Lights which are strong enough to get stopped down exposures with reasonable shutter speed and ISO settings need to be pretty bright. This gets expensive and less comfortable for your subjects.
The main thing to look for is how consistent the color temperature is (indicated by cri number--higher is better, be sure it is at least 92, preferably higher). The second is to see that it is bright enough for your needs. Third is to determine if the modifiers you want to use will work (reflectors, softboxes, fresnels) or to use flags and scrims. Then see if you like the price.
Kino Flows, Arri Fresnels and such are video and movie standards. They will probably be more than you want to spend, but they form a good benchmark against which to compare your choices.
I haven't used the Aperture lights, but this appears to be an interesting offering and they have an incredibly inexpensive fresnel which goes on it and, because it uses a Bowens mount (widely used industry standard--the most common at this point), it is easy to find modifiers. Bowens may be going, but their standard has a life of its own.
