8 Ιουλ 2024 · When out shopping for grow lights, savvy growers know to peek behind the wattage curtain and check out the photosynthetically active radiation (PAR) value, which essentially means available light for the plant to use. HPS lights consistently have lower PAR values than LED lights.

15 Οκτ 2024 · Theoretically, LEP’s luminous efficacy should exceed a HPS source by 15-20%, as no power is wasted on heating electrodes. In practice, light source efficacy of LEP (also known as “HEP” (high-efficiency plasma) or even simply “plasma”) grow lights range from 80 – 100 lm/W.
There's a key difference between LED grow lights & HPS in that LED's don't utilize bulbs. They are built with LED diodes, which can have a lifespan of over 50,000 hours! HPS bulbs on the other hand, need to be replaced up to a few times every year.
23 Οκτ 2019 · In 2020 LED lighting is the better choice in almost all cannabis growing applications. We’ve reached a break-even point where it no longer makes sense to invest in HPS technology despite the slightly lower startup costs. See the History of LED lights for a brief background on how LED’s have evolved over the years.
This High-Pressure Sodium (HPS) to LED Conversion Calculator will assist in determining the required LED wattage for a new LED luminaire to achieve visual equivalent lumens (VELS). The calculator helps assess the efficiency and financial implications of their existing lighting system.
8 Μαΐ 2020 · Do you plan to undertake that long-postponed high pressure sodium to LED conversion for the lighting in your home or office? LED is the newest and by far the best lighting technology available, using less wattage to produce high levels of brightness. HPS vs. LED
That means if you wanted the same brightness out of a 400w MH, you'll most likely find an equivalent LED grow light at a much lower wattage. See why we told you watts alone aren't a good indicator of a grow light's effectiveness on your plants? But just because a light is bright doesn't mean it has all the wavelengths your plants need.
