Right now I'm using a Patterson and a Jobo Maxilux LED, both of which are plugged into the same cord that goes into the timer, so they go off. I do own a Duke 50 sodium though. I don't use it now, preserving the impossible-to-replace tube life for the day I get back into RA4. That safelight has t be left on all the time. It takes several minutes to come up to full brightness and I believe can actually be damaged by switching transients, or at least have the bulb life lowered greatly, by being switched off and on by a timer. It used to stay on when I used it for all my work.
