Metal Halide Bulbs
We recommend replacing metal halide bulbs at least once a year. After a year of growing time your metal halide bulbs are only putting out half as much light as new bulbs will. Your eye will not notice it, but you will see a difference in how your plants grow after replacing your old bulb. We carry 100, 250, 400 and 1000 watt bulbs.

High Pressure Sodium Bulbs
High Pressure Sodium grow lights ( including Son Agro grow bulbs) should be replaced after 18 months of use. As with metal halide bulbs, light output decreases over time, but you still use the same amount of electricity.We carry 100, 250, 270, 400, 430, 600, and 1000 watt bulbs.

Convert your metal halide light to a high pressure sodiom light or convert your HPS light to a MH light, just by changing a bulb. We recommend replacing Conversion Bulbs after 12 months of use. We carry 360, 400 and 940 watt conversion bulbs.
