Now in the field of plant growth lights, everyone has heard of excessive daughter boards. If you don’t see the mentioned HLG LED growth lights, you can’t visit any forums about growth, usually in terms of luminescence. But how much hype is true? Is it just for marketing?HLG grow lights

Does this mean that these lights are not worth buying?

No, it is not. They are great lights and they perform very well. Although the company had problems in the past, it has changed a lot now.

Let’s take a look at HLG’s most popular quantum panel lamp first, and see the differences between them, and then we will introduce HLG 650R in detail, because this is their flagship product and can represent their level.

DeeTee Review :HLG grow lights

This unit is fine, but I still think that hps is the best. This unit is reminiscent of an advanced platinum LED unit with approximately the same growth rate. If it is cheaper, I would like to reconsider, but it does not surprise you.

Lower 1 star. An incredibly cheap carabiner with an original mount. The holes in the unit should be large or close to the corners. The board appears to be distorted and the white film around the LEDs is peeling off. Finally, a MADE IN USA sticker with MADE IN CHINA LED DRIVER LOL. SMH. Just looking at the parts, I think the whole unit is made in China. And it includes a 220-volt adapter or cord at a ridiculous price. The driver was also faulty from the start.

Alice Amanda Hen Review :HLG grow lights

Two ideas:

(1) The price is not very competitive. But the quality difference between HLG and cheap junk is worth it. The way they chose the optical spectrum is reflective. Many brands do it unexpectedly. The energy efficiency of the LED is stable. They don’t wear stupid 90 degree glasses or fall for the other traps that many brands use.

(2) HLG states that passive cooling is sufficient. (It probably is). But at full power, both the board and the controller get uncomfortably hot unless there’s a good flow of air moving through them. Fever is not suitable for longevity. Since the airflow in the store is bad, I took the CPU cooler that I had put in and put it on the controller. Running a 10-inch fan works too, but requires some airflow.

Very good overall design.

Stone Jack Baller Review :HLG 650R grow lights

it’s amazing! The lights consume 660w on high and 90w on low. I had a problem with the dimmer not working properly so I emailed the seller and two days later I received a new dimmer. The dimmer is very easy to replace and requires no tools, which is a bonus. The seller is top-notch. One of my downsides and the 4 star reason is that this dimmer is a cheap junk and doesn’t have full dimmer control like my cheap Mars TS3000 which is a very good dimmer. This light is the best and brightest I have ever had. I’d like for $ 1,100, but I wish I had a high-end fader that really dims accurately.

Great HLG light, but better dimmer. I will buy more form you.

The Samsung LM301H LEDs emit a full-spectrum white light with a color temperature of 3500K. That is a warm white (i.e. containing a lot of red-spectrum light) that is great for flowering, but also works well for vegging.

The additional LH351 LEDs add a 660 nm deep red light that give plants a huge boost during the bloom stage. It results in bigger and more potent yields.

The light emitted by HLG 650R grow light is very suitable for full-cycle plant growth, especially for flowering.

The HLG growth lamp is undoubtedly worthy of recognition, but if there is no good cooling system, it will become very hot under full power operation, and it will affect the lifespan. Another downside is that the price of HLG grow lights is not cheap, even more expensive than LED grow lights.

Netizen evaluation

You definitely need a vibrating fan to transfer heat from the quantum board and screwdriver. These fans are either fan-drawn or AC-cooled.

Even the middle well conductor alone can heat up to 50 degrees Celsius.

Also, 1 watt of shutdown equals 3.4 British thermal units.

The efficiency of HPS is about 44%, so a lot of energy is converted to heat.

Quantum plates are more efficient, so less energy is converted into heat. But watts are watts. And over time, the lights need to cool down, just like HID.

See this link behind an experienced grower, or in a forum that has been discussed in great depth with considerable science by an experienced grower.


You can also pay US $ 1000 for the top container accessory. From HLG (hlg buys parts in China and assembles in the US … still made in China)

Alternatively, you can pay US $ 350 from Alibaba for a Chinese quantum board with medium tray diodes with IR and UV turned off (trade guarantee, i.e. rollitup if protected item not described). Everyone uses them. With great success and excellent customer service)

10% difference between the upper container and the medium container

Difference between top bottle and robin 15%

HLG is very expensive. And customer service is not desirable.

If you think you need to spend more than US $ 650 on QB, 10-15% efficiency is chosen over the Chinese board.

However, most growers will not notice the difference unless all other individual aspects of their growth are marked to 80% of users. This plate is useless for you with its high price.
