These are just what I needed … lightweight, lower cost dew control. I tried using one wrap connected directly to the power supply to avoid the two hour shut off via the controller and it seemed to run too hot unless you are in the arctic circle somewhere. I purchased two and cut the ends of of each. With a small amount of soldering it was easy to connect them in series and then directly to the power supply. They then run at a reasonable 110-ish degrees in the house and should be close to the Medium setting if you were to use the controller on each. Should work great now wired in series and not having to worry about them timing out and shutting off.

1. 5.5X2.1 female interface design，easy connected to various 12V power inputs;
2. Protecting optical equipment such as telescopes from fogging or freezing. Compatible with astronomical primary mirrors of OD below 152mm(178mm) or Camera Lenses;
3. Three-speed regulator with medium-weak heating mode. You can adjust the temperature according to different usage requirements. Super-fast continuous heating, quick start heating;
4. The width of the 50mm belt will not interfere with focusing, and will not produce vignetting in the field of view;
5. Great heat preservation effect: imitating OK cloth, SBR, and Black-T three-layer heat preservation material, reducing heat dissipation, and no wrinkles on the inner surface after bending;
6. Uniform heating: the built-in aluminum film has a uniform heating surface and no dead ends;
7. TPE Silica power cord under low temperature won't become hard, also prevents internal short circuits.
