Twin ARC metal halide bulbs is literally two bulbs in one. Our Metal halide bulbs will greatly improve the lighting in your aquarium.  The Twin Arc bulbs are energy efficient due its design and will save you tons of money. They promote maximum growth and color in corals and other invertebrates. These lamps have better performance, color specs, and life hours then standard Single Ended metal halide Aquarium Bulbs. Twin ARC bulbs switch alternately each time the lamp is fired/turn on by providing maximum output and color consistency. The Twin ARC bulbs have two separate color temperatures.  By cycling the lamp (turning it ON/OFF) you can select the color temperature desired allowing you to set your light cycles to specific needs.  The Twin ARC bulb has built in circuitry allowing the bulb to be controlled by either manually, timer, or by lighting controller.  Twin ARC bulbs do not require any special wiring.
They work with any Electronic & Magnetic Ballast. Twin ARC bulbs DO NOT fire simultaneously.  They are fired in alternation each time BULB is turned on/off.
