How many lumens is a 250 watt HPS?
between 26000 and 29000 lumens
250 Watt. 250-watt HPS bulbs provide between 26000 and 29000 lumens of light in clear and frosted options.
Which is better MH or HPS?
It has been found that MH lamps are four to five times more efficient than HPS lamps. When considering their light generation, the HPS lamps produce light through the excitation of sodium. On the other hand, the MH lamps produce light through the excitation of two to five different chemicals.
How far should 250W HPS be from plants?
For 250W HPS, the distance of the lights from seedlings has to be between 10 inches (25.4 cm) and 14 inches (35.56 cm) from your plants. Place your hand where the seedlings are for about 30 seconds. If the light is too hot for you, that means it’s also too hot for your plants.
What is the difference between MH and HPS bulbs?
MH lamps provide a more natural appearance in color and are typically the choice for plants that have little to no natural light available. High Pressure Sodium (HPS) lamps provide more yellow/red spectrum, which is ideal for most plants that are actively fruiting and flowering.
