As you can see, there are various led grow lights on the market looking the same - square-shaped multi-bar design, possessing 4, 6, 8 light bars. But are they really the same? How could I distinguish a truly good multi-bar LED grow light? 
When the outside looks the same, we go to the inside. Today, we’re going to introduce you to 4 vital points to compare when you’re dithering among this kind of grow lights.
1.LEDs Brand.
Right now cultivators are highly recommended to Samsung LEDs. May it be possible that an 8-bar light declaring itself as Samsung lm301h/lm301b mounted while its price is only 300~400USD? Of course no.
2.LEDs Quantity.
Both have 8 bars, both use real Samsung LEDs, then what’s the next to compare? The answer is LEDs quantity. The LEDs are the most costly components in a light and which contributes to the efficiency and brightness. Mars Hydro FC6500 mounted 2688pcs Samsung LM301B while some brands only 1000pcs LEDs, but same or even higher power draw? it’s sly! Next, we’ll explain the defects of high power draw and fewer chips.
3.Uniformity of PPFD.
High PPFD in the middle and low PPFD on the edges can lead to uneven crop production with low yields at the edges.
4.Authentic Test Report.
First of all, Mars Hydro hereby promises that all our data is true. We can provide the original data test report. If you suspect that some brands exaggerated the data, ask for the original data test report.
Now we’re here able to answer our initial question: how to define a truly good multi-bar LED grow light?
