This is a unique way to provide your birds with healthy, full-spectrum light. This light design will fit cages with flat tops & arch tops. No hardware needed, eyelets fit securely between the cage bars. You can hang toys from the eylets also. The shade is attached to the grill with 3 wingnuts which allows you to change the bulb easily. The bulb is housed within the shade and will sit 4″ from the top of the cage. A FeatherBrite full-spectrum bulb (15w, 5500k, 91cri, UVA 4%, UVB .05%) is included with the light. This bulb provides full-spectrum light and minimal heat so the unit is only slightly warm to the touch. Durable non-toxic powder coat is used. A safety wire extender is attached to keep the electrical cord away from the cage. This feature helps prevent your pet from chewing the cord while they are in the cage. Available in BLACK, WHITE, SANDSTONE, CHAMPAGNE, SILVER HAMMERTONE.
