Will never understand them.
Have a 9 gang Crabtree grid panel. Originally fitted with Home Automation dimmers, in the 70s.
Many years ago, I got offered a carton of Dimmalite push button dimmers to fit the old Crabtree grid - after it had been changed. At a silly price. Before the days of CFLs and LEDs. They are rated at 400w resistive or 250w inductive. I like the action and looks. Touch the single button for on. And again for off. Hold it down and the level changes - a double press the other way.
Replaced all in the 9 gang panel with them, but of course kept the old Home Automation.
When dimmable LEDs arrived, did try one with this dimmer. Didn't work.
So basically left this room with tungsten.
With the increase in leccy prices decided to change the most used to LED. And intended fitting V-Pro dimmers to the Crabtree grid mountings - not an easy job. But out of curiosity tried one of the new LED golfball SBC in the table lamp on its own dimmer. And was surprised to find they dim just fine. As did a couple of GU10 lighting the inside of a (not used) fireplace.
So wondering if the LED design had changed? The original LED I tried did dim just fine with a LED dimmer. Not a minimum load thing either, as the golf balls are only 4 watt. And worked with just one.
