We carry a wide variety of replacement bulbs. Metal halide bulbs (clear and phosphor coated) are used for vegetative growth.

They come three ways – Horizontal (HOR), Base-up (BU) and Universal (U).

The HOR and BU bulbs (both high output) can burn only in those positions, but universal bulbs can burn in any position.

The sodium bubs (HPS) used for flowering and fruiting are all universal.

The conversion bulbs allow you to convert any halide system to a sodium system. Just screw in a conversion bulb and turn on your system!

Metal halide bulbs should be replaced every 12 to 18 months or when the inside arc tube begins to blacken.
