Zigbee Lights End Vs Router

For the first time I’m able to see the Zigbee mesh via Deconz and I have a few new Sengled lights that are end devices and not routers!

This comes as a shock as I thought all powered devices were routers by the Zigbee spec. How does one tell if the lights they buy are end or router? I can’t seem to find any indication.

The only way I know is to ask around.

There is some info on a couple of devices here https://www.zigbee2mqtt.io/information/supported_devices.html

That’s a great resource thank you, but I don’t see any reference to end or router devices for the lights.
