In addition, the light has a wired controller with an LCD monitor, which enables you to check detailed information, including current time, current mode, start and end time of running, current light color, and brightness. There are six setting buttons for you to set the working mode quickly.

Pros of 978 and 999 aquarium light
The 978 aquarium light has a separable adapter. As a result, if damaged, it is no need to replace the whole light. Also, the light is soft, and the color rendering index is close to natural light, which avoids causing discomfort for fish and humans. Additionally, the 978 light is suitable for freshwater fish-only tanks and planted tanks.
On the other side, 999 aquarium light is mainly designed for tanks keeping freshwater fish and aquatic plants, especially plants demanding low light. By scientifically adjusting, the three primary colors simulate natural light without flickering. It boosts the growth of aquatic plants and makes the water more sparkly clean from a visual. The ultra-bright LED light is beneficial to green aquarium plants and is ideal for freshwater fish and aquarium plants of low light but high brightness. Also, the 999 light has a power-off memory function for the use of an IC memorizer. Consequently, the setting of the aquarium light will not be lost after resuming work.
Which one is better for your fish tank?

On the other side, 999 light would be a better option for freshwater tanks. As for planted tanks, it is determined by the light requirements of your aquatic plants. Provided that the aquatic plants in your tank need low light but high brightness, 999 light would be a better choice. Aside from that, it is feasible to add the 978 light for a 10-gallon aquarium containing plants requiring low, medium, or high light levels. Just check the light specifications before purchasing.

Hi, I have the 978 light. Only one of the mounting brackets seems to be adjustable/removable. I bought risers and was hoping to replace the original brackets with higher ones. The bracket on the cord end won’t come out. Anything I’m missing?
Hi,
Would you please shoot a video and sent to [email protected]?
hygger customer service is waiting to solve the issue more accuracy for you.
Thanks
It sounds like you are not aware of the actual numbers and are using figures from imagination, as the difference between 10 cm and 35 cm is enormous according to the inverse square law. If the PPFD (it’s more correct to say PPFD, not PAR) is 153.4 at a distance of 10 cm, then at 35 cm it would already be only 12.52 PPFD.
Hi BigJeff,
The LED light installation distance is from 10 to 35 cm.
When measure the PAR value, the measure distance is the max 35 cm.
Thanks
Does the HG999 22w model have a PAR spectrum map? I want to understand which spectrum is stronger, red or blue. And “It is the measurement value under the normal installation distance.” – it’s about 30-35cm from the lamp to the bottom?!
BigJeff,
The HG999 22W has a 153.4 PAR.
And the red is stronger.
Generally, the LED light installation distances around 10-35 cm from the lamp to the bottom.
I mean, is 153 the value measured directly under the lamp, or at some distance from it? Since the higher the lamp is above the illuminated surface, the lower the PAR that actually reaches it.
Hi BigJeff,
It is the measurement value under the normal installation distance.
Hi, I buy HG999 22w , what are the Lumens and Par(ppf) on this device? and and from what distance are you talking about 0 or 30cm?
Hi BigJeff,
The HG999 22W, Lumens is 1480, and the Par is 153.4.
from what distance are you talking about 0 or 30cm? – Can this question be explained in more detail?
Thanks
May I ask what the PAR values are for the hg999 36w model at 12 and 18 inches?
Hi Ed,
The hg999 36W model’s PAR value is 196.4.
Its length is 34.4 inches, but not 12 and 18 inches.
Thanks

Hello, do you have PAR readings for these light at 12 and 18 inches?
Hi Mahesh,
We test all the light’s PAR value but we don’t have the table about it.
The 12-18 inches PAR is about 70 PAR.
Thanks

I have 4 model 978 Hygger lights. Are they considered low, med , or high lights?
Hello, Wiliam. Actually, the light intensity of 978 light varies with different power. 14W 978 light with 817 lumens can be low light. While 18W with 1075 lumens and 22W with 1583 lumens belong to medium light. Also, 26W with 1662 lumens, 36W with 2778 lumens, plus 42W with 2815 lumens can be high light. Just take it as reference.
