These cartridges are exactly what I was looking for for my garage's LED lights. There's a pair in this listing, meaning you get two outlets. This allows me to power two LED tubes from one end and hold the plastic safety pins on opposite ends of the tubes. Simplicity. I haven't tested the caps to make sure they're waterproof, but I'm sure the caps keep condensation away from the light's power terminals. I would give 5 stars if there were 4 sockets for the price of 9€.
