18.5mm diameter, 7.7mm thick + 3.7mm for the flange on the back (see photo on mfgr page https://niteize.com/ziplittm-led-zipper-pull ). Output is about 1 lm, wide flood, similar to using a phone screen to light your way. Definitely a functional light not just a location marker. Smallest light that I actually know where to buy. Drops ok edgewise into NDUR match safe and of course you can use the space around it. Weight incl battery and non removable pull cord, around 2.5g or 3g. More later.
