What is COB LED grow light?
Reviews of the Best COB LED Grow Lights on the Market. ... COB – which stands for [Chip-on-Board" – is a recent development in LED packaging technology where multiple LED chips are mounted directly onto a single substrate to form a singular module.
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
Mga Bentahe.
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. 245W 450W 630W 400W COB led grow light parameter

Ano ang bumubuo ng isang mahusay na LED lumago liwanag?
1.PPFD Halaga: PPFD ay photosynthetic photon flux density. Kapag pumili ka ng liwanag ng halaman, dapat mong ihambing ang mga halaga ng PPFD ng iba't ibang mga ilaw ng halaman. Ang mas malaki ang halaga, mas mahusay ang paglago ng halaman.
2. Hindi sapat na kapangyarihan: Dahil ang aktwal na kapangyarihan ng liwanag ng halaman ay laging nag-iiba sa iba't ibang mga kondisyon, ang lahat ng mga nagbebenta ng Amazon ay gumagamit ng rated power upang ilarawan ang lakas ng produkto dahil ang rated power ay pare-pareho. Kapag pumili ka ng isang LED lumago liwanag, ang rate ng kapangyarihan ng liwanag ng halaman ay isang reference, at mas mahalaga ay ang aktwal na kapangyarihan.
3.Core coverage: Bilang karagdagan sa itaas sa itaas, kapag pinili mo ang isang liwanag ng halaman, kailangan mo ring ihambing ang lugar ng pabalat ng iba't ibang mga ilaw ng halaman, siyempre, ang laki ng core coverage area. Sa pangkalahatan, sa yugto ng pagtubo, maaari mong i-hang ang liwanag ng halaman mas mataas at ang lugar ng pabalat ay mas malaki. Sa pamumulaklak yugto maaari mong i-hang ang liwanag ng halaman mas mababa at ang lugar ng pabalat ay mas maliit dahil ang planta ay nangangailangan ng higit na liwanag sa yugtong ito. Kailangan mong ihambing ang iba't ibang mga lugar ng saklaw upang piliin ang liwanag ng halaman na nababagay sa iyo.
