Which PhytoMAX-2 LED grow light is equivalent to a 1000W HPS or MH?

Which PhytoMAX-2 light do I need to replace my existing grow light?


There are a lot of different grow lights on the market, and each one is different in terms of the light output it provides. Even within a grow light technology, such as high pressure sodium (HPS) lights, there can be big differences- double-ended HPS bulbs are much more efficient and put out more light per watt than single-ended HPS bulbs, the efficiency of HPS bulbs changes with the wattage they are run at, and different manufacturers' bulbs give off more or less light. Determining the correct LED grow light replacement for your existing HID bulbs can be confusing.

Rather than comparing total light output (PF), which is affected by reflector efficiency, this table shows what PhytoMAX-2 light models are equivalent to for other (average) lights in terms of light actually delivered to your plants and actual growing power.
