LED Bulbs: (90pcs) High Intensity 5W Epiled/Bridgelux LEDs. The optimal full spectrum provides plants with everything they desire in the natural sunlight. The secondary optical lens magnify PAR and increase canopy penetration by up to 200%.Upgraded 3.2" front-fans for the first time plus big aluminum cooling heat sinks (0.8" height) are easy for heat dissipation quietly. We stand by our good-quality products and your satisfaction is 100% assure. To meet the different spectrum demands of vegetative and flowering stage of plants growth, the PAR450 uses separated R, W and B dimmer to control the red, white and blue spectrum individually. Please turn on the 100% brightness of R, W and B channel for flowering stage.
The secondary optical lens magnify PAR and increase canopy penetration by up to 200% is scientifically engineered to keep the balance with excellent PAR Output and suitable Coverage. This design focus more light on the plants, at the same time will not far too concentrated in the middle of the growing area which results in stunted plant growth and sunburning. Solid Construction, Efficient Cooling System. The PAR450 is a full-cycle top-lighting solution with PPFD up to 600 µmol/m2/s at 24 above canopy. With the ability to scale from vegetative growth to higher light intensities in bloom, no other lighting systems is needed over a 2'x2' flowering area.HOW TO COMPARE LED GROW LIGHTS? If you have been researching LED grow lights for your plant growth facility, you have likely been bombarded with a variety of metrics that lighting manufacturers use to market their products: watts, lumens, LUX, PAR, PPF, PPFD. In order to explain the correct method for evaluating a horticulture lighting system, let's first highlight two of the metrics used today that you need to avoid. RULE 1: DON'T FOCUS ON THE WATTAGE OF THE LED'S.
Do you use 5W, 10W, or 15W LEDs? We are asked this question on a frequent basis, but the wattage of the LED use in light does not tell you anything meaningful about the lighting system's performance since LED and fixture efficiency varies widely.
Remember, the LED wattage is a system input, and growers care about the system output--PAR Output. Hence, the lighting system using 10W or 15W LED wattage doesn't deliver more light to your plants than lighting system using 5W LED wattage. RULE 2: DON'T LOOK AT A SINGLE PPFD MEASUREMENT.Unless you are growing a small plant directly under your light, a single PPFD measurement doesn't tell you much. However, unless you are only growing one plant in this exact location, you need to know how much PAR is being distributed across the entire canopy. Three important questions you should look to be answered when researching LED grow lights are. How much instantaneous PAR from the fixture is available to plants (measured as PPFD)? How much PAR is being distributed across the entire canopy?
How much wattage is used by the fixture to make PAR available to your plants? The three key metrics of the PAR450 used to answer these questions are. PPFD directly under the Fixture.
PPFD is photosynthetic photon flux density. PPFD measures the amount of PAR that actually arrives at the plant, or as a scientist might say: "the number of photosynthetically active photons that fall on a given surface each second". PPFD is a'spot' measurement of a specific location on your plant canopy, and it is measured in micromoles per square meter per second (µmol/m2/s). PPFD over a 2'x2' Area.
If you are growing over a 2'x2' area, you need to review the PPFD levels over the entire area to calculate the average light level the lighting system is providing. If you only had a center point measurement you may assume a fixture is extremely powerful.
However, you would need multiple measurements across the 2'x2' grow area to calculate the average amount of PAR that is provided by the fixture. In general, for well-designed full spectrum lighting system, the higher actual power draw is, the higher PAR Output a lighting system emits to plants. VIPARSPECTRA PAR450 Dimmable LED Grow Light is scientifically engineered to keep the balance of the PAR/Lumen output and coverage. Individually adjustable Red, White and Blue dimmers allow precise 3-channel spectral control.
Compares to traditional 300 watt HPS/MH while consuming only 213 watts! Perfect for a 2.5x2.5 vegetative coverage at 32 while 2x2 flowering coverage at 24.
