4xCREE COB 2000W LED Grow Light Full Spectrum UV IR Plant Grow Lamp for Indoor
How good are the COB LED grow lights?
Integrated LED is generally a different name for COB LED in the market, but in fact it cannot describe the characteristics of COB LED clearly. COB refers to Chip-On-Board, which directly encapsulates a small power chip on an aluminum substrate for fast heat dissipation, with a small chip area, high efficiency of heat dissipation and low driving current. Therefore, it has high heat dissipation with low thermal resistance and high thermal conductivity. Compared with ordinary SMD LED, it features higher brightness, lower thermal resistance ( 6℃/W ), lower light attenuation, higher apparent index, perfect light spot and long life. 
Testing, LED plant lights are very suitable for plant growth, flowering, and fruiting. As an artificial supplemental light, led plant lamps light can be enhanced anytime in a whole day, what effectively extend the lighting time by plants.
Whether it is sunny, cloudy or rainy, led plant lamp can reasonably and effectively extend and scientifically control the light needed for plants. Plant laboratory, plant grow light can completely replace natu. Ral light, to ensure plant healthy growth and promote faster and better growth. H/HID/CFL lamp, LED growing light can improve plant efficiency and save electricity!
Phlizon 2000W COB LED Grow Light Features
Uses 451 watts - save about 50% on your electric bill over HID lights
Equivalent to a 800 watt HID system - but costs less to buy AND to operate
Ideal spectrum for plants - the perfect light for all stages of growth, with peaks on red and blue and healthy amounts of all other colors (which is what plants need)
4 by 4 foot core coverage - effective coverage for plants with high light requirements is just a bit less (3.8 by 3.8 feet)
CREE COBs - high quality 50w COB LEDs provide both warm and cool full spectrum white light
Supplemental Diodes - 10w diodes add the perfect amount of red, blue, UV, IR and white light to the two white COB spectra
Dual switches - saves money, since you can turn off some of the diodes when you don`t need full power
Rated for 50,000 hours - 4-5 years with no bulb changes
Great free extras - grow light glasses, thermometer and humidity monitor hangers, and adjustable rope ratchets
Advantages
The two strongest points of the Phlizon COB lights are the high output and the perfect spectrum for plants. The coverage area is also good and I like that they give you a lot of free extras, although not all of them will be useful to everyone.
The output on this light is pretty incredible, especially when run at full power. It is about equal to a 800 watt HID system. Dead center below the light, it gives you a PPFD of 2161 umol/m²s when hanging at 18 inches. That is double what any other so-called (more on the reason for the `so-called` in the disadvantages section below) 2000w light can do. This light is very similar to the much more expensive Optic 4, in that they both have 4 COBS surrounded by supplemental diodes. But this light costs about half as much and gives you more power. It also gives you a larger effective coverage area of about 3.8 by 3.8 feet. It only uses 451 watts to provide this coverage and output. Plus, you don`t have to run it at full power, which saves you money when you don`t need quite as much light intensity.
They feature 4 COBs: two emit a warm white light with a color temperature of 3000K (contains more red) and the other two emit a cool white light with a color temperature of 6000K (heavier in blue). The COBs are supplemented by 10w diodes: 68 of them are red (660 and 630 nm), 10 of them are blue (470 nm), 6 are cool white (6500K), 4 are warm white (3000K), 4 are UV, and 4 are IR. Together, they produce a color spectrum with peaks in the red and blue wavelengths and a good amount of light in between (orange, yellow and green). This is the perfect lights for plants and will take them through every stage of development. 245W 450W 630W 400W COB led grow light parameter

Compare LED cresça leve com HPS/MH tradicional CROVE LUZ
O que compõe um excelente LED crescer leve?
1.PPFD Valor: PPFD é densidade fotossintética de fluxo de fótons. Quando você escolhe uma luz vegetal, compare os valores de PPFD de diferentes luzes da planta. Quanto maior o valor, melhor o crescimento da planta.
2. Power: como o poder real da luz da planta sempre varia de acordo com diferentes condições, todos os vendedores da Amazon usam a energia nominal para descrever a potência do produto porque a potência nominal é constante. Quando você escolhe uma luz de LED cresce, a potência nominal da luz da planta é uma referência e, mais importante, é o poder real.
3.Core Cobertura: Além dos dois acima, quando você escolhe uma luz vegetal, também precisa comparar a área de cobertura de diferentes luzes da planta, é claro, o tamanho da área de cobertura do núcleo. Em geral, no estágio de germinação, você pode pendurar a luz da planta mais alta e a área de cobertura é maior. No estágio de floração, você pode pendurar a luz da planta mais baixa e a área de cobertura é menor porque a planta precisa de mais luz nesta fase. Você precisa comparar diferentes áreas de cobertura para escolher a luz da planta que combina com você.
