I am going to have 3 different Colors of c7s on my roof line (White, Red, Green) and is going to take about 700 feet of wire with c7 sockets. I planned on buying a 1000 foot long spool and since I will have some extra, I thought I might as well run another channel.

I was going to do just another color but I thought it might be cool to have it all be white twinkle c7 lights. This way I could have all the white lights on and then switch it over to the twinkle ones for a cool effect.

My concern is I really don't know how the twinkle lights work. I am guessing that each just sort of twinkles on their own. My question is do these have to "warm up" before that start twinkling? If they do, I was wondering if I could maybe keep them "warm" by dimming them to a low setting (5%?) so you could not really see them but they would starting twinkling when you brought them all the way up.

Anybody have any experience with the c7 twinkle lights? I will be getting them from action lighting.

The C7 twinkle lights that I have seen do need a warm up time to twinkle (bi-metal contact). The (run dim ) idea should shorten the warm up time but I have no real world experience as to the effect it will have. The Action Lighting C7s may be a different technology.

This is true, but I used them last year (C9 twinkle actually) and held the power on at 18%--not enough to visually detected but enough to substantially reduce the delay-to-twinkle." In the same display, an 18 foot Bethlehem star, we varied the voltage of the clear bulbs to achieve light gold coloring.

As Dan said they use a "bi-metal contact". The 2 pieces of metal are fused together. They heat up at different rates which causes one to pull on the other making them bend. When they bend they break the connection and the bulb goes off. When they cool the connection is made again and the cycle repeats. This is the same way thatan automotiveblinker module works (the older ones at least). The difference with blinker bulbs is that there isa blinker thingiein every bulb. Therefore they will as you suspected each blink on their own. They will also blink at different rates giving a nice random effect. If you look into the bulb you can see the contact especially since your bulbs will be clear. Compare a blinker bulb to a non-blinker bulb and the difference will be pretty obvious. Keeping them on at a lowsetting shouldhelp "pre-heat" the contact in the bulbs but there will still be a delay. You could also figure on switching them on a second or 2 before you turn the steady burning channel off. You will have to play around with it to figure out how to get the best results. Outside in the cold it will take longer for them to start flashing.
