I’ve grabbed a kit off the shelf and measured some LEDs from it. I make the LEDs to be around 6.5mm x 6mm. I’ll have the dimensions added to the product page.
EDIT: I noticed the dimensions listed in the description of Small Inductive Wireless LEDs - 10 Pack - Blue were quite a bit smaller than the LEDs from the coil kit, so I measured them too. It seems there’s a bit of variation between each LED, but they’re all smaller than 8mm x 6mm
They are quite a lot smaller than the coil in the kit, this photo shows the scale the best.
While Adafruit don’t specify a current requirement, our 24V 1A appliance plug pack should work well:
If you’re looking for something battery-powered, let us know, but keep in mind that 24V systems are usually big lead-acids, or dangerous 6S LiPos, or inefficient boost converters, so it adds a good deal of complexity over just the plug pack I linked.
Let me know if you need any more info
