- Power Draw is measured with a Kill-a-Watt after a 30 minute warm-up.
- Average PPFD is an average of all measurements taken from all heights (6" to 36" in 2" increments).
- Bang for Buck is calculated by multiplying the Average PPFD by the surface area of the grow space (square meters) and dividing by the price of the lamp. Higher is better.
