I was looking into getting a good bulb because the plants inside my chams cage have mostly died due to not enough light. But there is a 3 1/2 ft tall pothos in his cage, he's in the zoomed large screened cage. What i am wondering is what wattage of jungle dawn should i get? Would the 40w be too much? I like that you can screw it into a regular dome fixture and set it on top of the cage between his heat and UVB strip.
