I'd go with this dimmer: https://www.amazon.com/Leviton-TBL03-10E-Tabletop-Control-300-Watt/dp/B00A80756O/ref=sr_1_4?keywords=TTCL+100H&qid=1567435080&s=gateway&sr=8-4

It's pretty much the same, but handles LED more consistently (less flicker as you attenuate the voltage going into the light. Generally you don't have to worry about flicker, but sometimes it happens when you dim all the way down to like 10%. Dimmers for LED seem to handle at least that aspect better).

For power, you will need an extension cord unless you want to plug the light directly into an outlet just inches away. Usually, you plug the Quasar power connector into the extension cord and then you connect the extension cord into the dimmer and then finally the outlet. My suggestion, is to either buy the lightest weight extension cord you can find, just something really thin, as it will drag less on the light if you have it gaff taped to say, the ceiling / walls or anywhere else.

I started by using cheap 15 to 20 ft small extension cords and then finally moved onto using zip cord / lamp wire. The advantage to using zip cord is that it is very very light weight and can be hidden easily and the best part is that you can make your own cords extremely easily, any length you want and add plugs anywhere along the cord quickly by using add-a-tap plugs (allows you to connect multiple tubes to the same cord).

Creating your own cords is very very convenient and easy to do.
