It’s a 45w Kmashi grow light. Used to be able to get them on Amazon for close to $20, now I can’t even find them on Kmashi’s own web site. Been using this alternative bulb and like the results of it just as well. “CANAGROW 35W LED Grow Light Bulb, Grow Lights for Indoor Plants, E26 Plant Grow Light Bulb, Grow Lamp for Hydroponic Greenhouse Succulent Flower Veg and Bloom https://www.amazon.com/dp/B07K15XHYR/ref=cm_sw_r_cp_api_i_9hUGEb4Y57N8T”.
