There are other items that may be tip-offs as well such as the sloppiness of the print around the LED, flat vs textured appearance of the label stock etc. You’ll need an SSR rated for inductive load, usually a random triggered type not zero-cross type. I want to receive an additional SMS with a notification Your phone number: Best way to do this is to attach heatsink to backplate. You can operate without heatsink if load is switched in periods, but for constant driving it would be better to use minimal heatsink to lower junction fohek and extend operating life.
