I just got a little LED light with those wire leaders on them that would cause the same problem in my 5' high tent so took them off and attached directly to the clips on top of the light so now I can go up to a couple inches from the ceiling in there if need be.
This is it downstairs with those leaders attached hanging from the chains I use for everything that needs to hang from somewhere.
I could see that wasn't going to work in the tent so took the leaders off and hooked short pieces of chain across the hooks on the light. Those short pieces can be easily shortened even more so they will lie almost flat against the light to get it up as high as possible. Then just chain to hang it up. Height adjustment is dead easy with the S hooks and I've been doing it like this for 20 years. Stupid ratchets get loose and drop lights into the canopy, cost more and aren't near as easy to adjust as a hook IMO.
You can cut the chain so it's last link where you made the cut forms a hook like where it attached to the cross-chain on the light. Saves a couple of S hooks and can easily support 10lbs each without bending.
