The on/off switch is built in to the base, allowing you to control the lamp separately from the rest of your landscape lighting fixtures. This small, powerful lamp provides you with the lighting you need to be sure the steaks are cooked to perfection. No more poking at meat in the dark, or squinting against the glare of a porch light while using your grill. This elegant, sophisticated fixture illuminates your grill space and adds a touch of class to your deck or patio area. Requires a 12-volt transformer.
