Lighting is always a good thing. These are some lights I own and highly suggest. They range $30 and up. Neweer 2 Light System comes with two table top tripods and filters. They plug in via USB. Excellent if you're just starting out. The only negative thing is the tripod's take up table space. They aren't the tallest tripods.
NEEWER GL25B 12.9" Streaming Key Light comes with a remote and table mounted stand, plus it emits a softer light. You only get one but its worth the initial investment. The table mount is fantastic in saving table space!
Neewer Table Mount with Arm is an exceptional addition if you want to save space. It mounts to your table top or desk. You can add a light to the top, and your camera (or phone) to the arm. Works great!
Neewer 2 pack table top mounts. These are fantastic too! Just a two pack if you already have lights or if you've purchased the 2 pack Neewer LED Lights. You can ditch the tripods and attach those lights to your table.
