Sturdy durable construction with fire-resistant iron housing. VEG and BLOOM switches are suitable for each growing phase. Daisy chain feature assists growers to connect multiple lights together with fewer outlets. Comparable to traditional 300W HPS/MH while consuming only.
Perfect for a 2.5'x2.5' vegetative coverage at 24" and 2x2' flowering coverage at 18". We will offer you professional guidance to help you and your plants grow better.The Features of VIPARSPECTRA 450W LED Grow Light. Replaces a 300 watt HPS/MH. Dimensions: 16.1x8.3x2.8 inches. Item Weight: 8.4 lbs. Use for all stages of grow and flowering.
High Intensity 5Watt Bridgelux/Epileds LED Chips. Number of leds: 90 PCS.
Vegetative coverage at 24 Height: 2.5 x 2.5ft. Flowering coverage at 18 Height: 2 x 2ft. The Reflector Design increase PAR Output by 50% is scientifically engineered to keep the balance with excellent PAR Output and suitable Coverage. This design reflects more light to 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. The daisy chain feature which assists growers to use multiple lights together with less outlet.
No additional cords is needed, just simply plug in the provided power cord into the second light's outlet to achieve connection among multiple units. 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 2.5'x2.5' Area.
If you are growing over a 2.5' x 2.5' 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 2.5×2.5 grow area to calculate the average amount of PAR that is provided by the fixture. · 1 x Upgrated V450 LED Lighting. · 1 x Hanging Kit.· 1 x US power cord. · 1 x User Instruction. Extremely bright, do not look directly at the LED bulbs when the light is working. No extra ballast is needed.
Light housing's temps would become higher after severval hours. Do not touch the operating lamp. Can be controlled by Timer. In ambient not exceeding 104°F(or 40°C).
