This project is in two parts;
I would be very grateful for help in either or both parts.
Please ask for clarification if you need it.
I have a 1000w digital HID (High Intensity Discharge) lighting ballast:
- can I run more than one light if I can make the load "appear" the same?
for example, if I had two pairs of lamps - each pair running in series,
would that work? (I am more worried about what I believe the ballast does which is sending out many pulses per second might not feed all the lamps.)
............------lamp-------...........------lamp-------
---------........................-------........................-------------
............------lamp-------...........------lamp-------
(ignore dots, used as spacers)
- I have one lamp outside for security and one inside my workshop for lighting.
I can manually pull the lead out
(from the mains side of the ballast first, not the lamp side of the ballast, which I understand is dangerous)
and switch over lamps while keeping just one ballast working.
I want to do this automatically as my entry/exit times are the same.
I want to use a contactor relay connected to a mains timer. I also want to use only one ballast. Is there a way to safely switch over the operating lamp from the ballast end?
..............................................................................----lamp 1--
---240v--BALLAST--- (project/timer/contactor relay)-----
..............................................................................----lamp 2--

Many thanks for looking in; I appreciate any help.
