Product Description

Phlizon 450W Cob Led Grow Light

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.

Output and Coverage

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.

Power-Saving Switches
This light has two switches: one labeled [veg & bloom on" and one labeled [stronger on". I like the switches, but hate the labels.
The veg/bloom" switch toggles the 10w supplementary diodes and the [stronger" switch toggles the COBs. The names of the switches seem to suggest using the 10w diodes for veg and bloom and turning on the COBs only when you want more power.

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.

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

Compare LED Grow Light to traditional HPS/MH grow light



1.PPFD Value : PPFD is Photosynthetic Photon Flux Density. When you choose a plant light, you should compare the PPFD values of different plant lights. The larger the value, the better the growth of the plant.

2.Actual Power: Because the actual power of the plant light always varies with different conditions, all Amazon sellers use the rated power to describe the power of the product because the rated power is constant. When you pick a LED grow light, the rated power of the plant light is a reference, and more importantly is the actual power.

3.Core Coverage: In addition to the above two, when you choose a plant light, you also need to compare the cover area of different plant lights, of course, the size of the core coverage area. In general, in germination stage, you can hang the plant light higher and the cover area is larger. In flowering stage you can hang the plant light lower and the cover area is smaller because the plant needs more light at this stage. You have to compare different coverage areas to choose the plant light that suits you.
