These are the two photo controls I have. I'd bought the clear Tork at Lowes a while ago. Then yesterday I saw the blue one at Lowes, I couldn't find them before, but they are with the lamps. So having always liked blue photocells, I got one. It's cool because it says you can program it to turn off after a certain time at night and back on in the morning. Plus it's supposed to memorize the time and set automatically for daylight savings.
I found Lowes had that clear Tork one for 120V and a maroon one that's for 277V units. Lowes had a clear one similar to the Tork, this blue Defiant one and another blue without the programmable feature. Walmart had a clear Brinks one.
It's interesting the size difference between the two. I mainly got it for my GE 201SA, but I'll probably keep the clear one in case I get another HID and need it. I do like clear ones too.
