How does LED grow light wattage convert to hps wattage?

It was explained to me that more wattage in your light source, either it be LED or HPS, the more penetration your light source has. The comparison was explained to me like this: for every 100 watts of HPS, you need 70-80 watts of LED to equal the same penetration. IE 800watts of LED = 1000watts of HPS.

As a reminder, when I say "you need 70-80 watts of LED to equal the same" I mean you need 70-80 watts of actual draw power.

HPS to LED conversion (HPS wattage x 0.8 = LED equivalent)
LED to HPS conversion (LED wattage / 0.8 = HPS equivalent)

 Advantages of LEDs over HPS

Efficiency – LED diodes are very electrically efficient, which could save you money over time (though the jury is still out when it comes to whether LEDs get better yields than HPS watt-for-watt). Additionally, where an HPS bulb needs to be replaced every few grows to maintain its brightness, individual LED diodes keep their brightness practically forever. With an LED grow lights for weed, it’s almost certain something else will break on the lamp before any diodes start losing their brightness.

  • LED grow lights last six times as long!
  • Eco-friendly LED grow lighting uses no toxic metals.
  • Energy savings range from 50%-70% over HID lights.
  • No cooling necessary; no plant burn and decreased risk of fires.
  • LED directional lighting requires no reflectors.
  • Maximum chlorophyll absorption and flower production.
  • Discretion assured — no thermal footprint.

Advantages of HPS over LEDs

HPS grow lights are much more consistent among makers, making it a bit much easier to comparison shop.
HPS light setups have a less expensive start-up price, however, the price gap in between equivalent HPS and LED grow lights has become considerably less as LED grow light setups become less expensive each new generation.
HPS bulbs provide a tremendous level of raw light strength so they can create great yields, especially when working with very big plants.

How Much Marijuana Can I Yield by using 8×8 Grow Tent? 420 Guide

How much marijuana can you yield indoors? Lights are of the utmost importance when you’re growing indoors.

Likewise, a grow tent for marijuana with 1200 watts of light can yield 1.2 kilograms or 42 oz of cannabis. Having the right equipment, adequate nutrient solutions, beneficial air quality, and other valuable factors is important for producing the highest yields possible. Making sure the plants have space to grow is also key.
