UVB Light Dedicated clip-on socket These two items are included. Please carefully review the product description and photos as these are used items. If you have any questions, please feel free to ask in the comments. I used these for raising a budgie. The socket was used for 3-4 years, so there is stickiness and hardening/chipping of the resin on the clip due to deterioration. I have confirmed that it powers on and functions, but it shows significant signs of use. The light is new, but I have opened it and turned it on a few times to check its condition.
