A look inside the SGS-160 (warranty fan replacement)

USPS must have dropped my pretty new light, arrived with a broken fan (impact fractures).

I emailed them(A51) at 6:02pm on the day it arrived. By 6:17pm I was hanging up the phone with one of their courteous employees, and by 8pm I had tracking info for the replacement part. Fan showed up on time (first class mail) and I put it in today (arrival date).

Some of the pics are from before the fan was repaired, I had it in my enclosure for about 3 minutes and snapped a couple pics. I didn't have it on long enough to run hot, or really even heat up. The enclosure isn't done yet, but for reference, the dimensions are 21.75" x 30" x 48" (internal dims)... passive intake at the bottom, scrubber/exhaust out the top, total 18.3 cubic feet.

Actual dims of the SGS-160 are 11.875" x 18.125" x 3.5", main case body is 2.8125" thick, brass hangars make up the difference.

Side note: I was warned to make absolutely sure I plugged the correct 2-wire connectors back together, or the reds would fry. You will see the difference in power supplies. I didn't have to disconnect any of the wires (besides the one fan), I just cut the zip-ties to get enough slack, and replaced them upon reassembly. There were 3x zip-ties that I cut and replaced. It appears the whites are ran @ 700-750mA, and the reds ~600mA. I didn't grab my DVOM, but I'm not testing them (no need to).

New fan (and my PH meter showed up today too)


grille removed to show the problem


Broken


I was authorized to remove these:


New fan installed


shot from further back



close ups






Outside - reassembled





Hope you like my sheets, they're new.



Red and whites on


Just whites


Comes with these rope hangers, hooks are from HD.




Obviously my cords are not going to be dangled so awkwardly once I actually use the light.

(side note, $20 DIY carbon filter doesn't cause too much drag on the fan either, nice and quiet)

I don't have a fancy camera, this was with my phone because my "real" camera has a MIA charger.


Thank you for reading/looking.
I'm posting this because I know somebody might appreciate it, I like helping people. Constructive criticism on anything I've done is welcome.
Overall I'm quite happy with my purchase. I would do it again, but hopefully not until I need/want to expand.

Thanks, I'm doing an experiment with panels of Whiteboard. I can write on my walls with dry erase markers, not that I'm going to (other than the thin strip on the left you can barely see in the last pic), but the main purpose is that I can clean super easy.

​Hey, very good pics, but I cannot see the fans' transformer yet, there are three drivers, two of them(the 55-85V ones)run the 48pcs white LEDs; and the 40-55V driver runs 24pcs Red LEDs. Is there a ground wire connected with the panel please? If not, is there any LEDs dim bright after turnning off the switch?
Each fan consumes 1.5W power, and what's the LED transformer conversion rate, I suppose it is 90%.
Total actual draw 155W-3W( fans consumption)-15W(10% LED driver consumption)=137W actual output energy for plants.

The fans have a 2-wire (like 24awg or smaller) that come off of each driver for the whites.
The ~600mA supply is just for the reds.

I'll see if I can pick up a meter to see actual power draw.

Plugged it in last night for about an hour to test the box for light leaks. Even after almost an hour of running in a the box (18cu.ft) with zero air circulation(only one plug was within reach), the temps only rose from 77F to 86F.

Edit: The whites do not dim when the reds are turned on.

The inner parts is kind the sames as the old version LED grow light.I am sure EH can ask his supplier to have a better case of the driver built, say aluminum case.

Hyall, I was wondering if it was possible to have quieter cooling fans?
I own a area51 - af240 (450w) and its a little noisy imo.
Any help would be more than welcomed :)

Thanks buddy :)
Just a last question, if I'm not wrong, it runs a 120mm fan but should I look into the one that got the highest CFM, dBA and RPM?
10x

ideally not less cfm than the original.

if that info isn't available, I'd shoot for 80(ish)cfm but as quiet as possible.

If the fans are inline with the diodes on the driver, does the consumption and/or current/volts play a role in his choice?

@LEDmania- what panel is that a picture of torn down?

That was a 120W grow panel with 112x1w LED chips, its inner structure almost the same as the 55x3W, 119x1W penels.

I am sure everyone would like to have a quieter fans, but we have to consider the thermal management, if the fans are too weak, they can dissipate the heats, if the fans are too big, the inner structure of the lamp has to be modified.
The key is to balance the heat and the thermal system at the most economic production cost.

Just shot some more photoes of the LED panels from two different Chinese manufacturers.

I got in touch with their customer support and the guy suggested me the cooler master sickleflow 120 2000 rpm
