    Question regarding lamp for 24 VDC bulb with E26 base and A19 profile

    Can I convert a conventional 120 VAC lamp into a 24 VDC lamp by switching it over to a 24 VDC bulb with an E26 base, and by wring said lamp into the "lamp" outlet of my Tracer MPPT charge controller?

    you could, and you would regret it when someone plugs the lamp into 120VAC.

    Also, at DC, the switch in the lamp may arc weld itself.

    Also, be sure the lamp does not draw more power than the terminals on the controller are rated for.

      I'm looking at a 5 Watt, 24 VDC (actually 22 VDC to 30 VDC) E26 bulb. If I cut the plug off in order to insert the wires into the charge controller, then there will be little chance of plugging it into the 120 VAC circuit afterward. Good thinking about the switch arc welding itself. I did not consider that. Any real chance of it at 5 Watts?
