Phlizon Veg Flower COB Grow Light

The Phlizon COB lights beat any similar lights in terms of output and spectrum. They do cost a bit more, but the additional power and better results the spectrum will give you more than make up for that difference. It topped both the list of the best 2000w LEDs and of the best COB LEDs.

And even with the higher price, these lights are still priced far below top brands. They are even priced far below the top BUDGET brands, like Optic.

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)

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.

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.

Spectrum

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
