Thank you for inquiring about vintage LED # ST19/S/CL/FILED/12. This dimmable LED bulb can be operated with a normal ON / OFF switch.
The 40W rating of your fixture is most likely a rating for incandescent bulbs. Incandescent bulbs generate quite a bit of heat along with light. Using a 40 watt equivalent LED generates almost no heat, so you will be fine with a 40 watt equivalent. If it suits your needs you cam probably get a brighter LED bulb and still be fine.
Thank you for your question. This bulb is exempt from title 24, it is only 250 lumens,
A dimmer seems like a dimmer to me. I had these on a Lutron smart dimmer and it worked perfectly.
50 lumens, equivalent to 40 watts
