The aluminum holder quite hot also.... Not as imagine...

[sacy]

Yup it is normal to be hot for passive cooling module. As long it is within the thermo limit. It should be fine

Hi Sacy, thanks because I scare it will melt the acrylic....

Do you know how to connect the LED downlight type with 2pin ? Can I just connect to my use cooling fan adapter which is 12v output. Need to put on top of my cube tank...

Thanks...

[sacy]

Your acrylic will not melt. But if I'm not wrong, if it exposed to prolong heat at around 80c to 90c it will slowly loose it shape,like bent or warp. So do check on the temperature on your acrylic. Be safe try not to let the acrylic to heat up to 70c

For the downright thing, I don't understand. Got photo?

But to counter this problem. Why not just lift up you light set about 3cm away from your acrylic.

Still thinking of how to lift/hang the led strip.....
As for the downlight led, same as your picture post.. How you connect those led . Are yours is screw type or pin ?
Thinking of hang at lower tier of my tank ImageUploadedByTapatalk1344421764.580634.jpg
And think of just buy the bulb and use old cooling fan adapter connect.
Is this work.?
Thanks

My is not the Down light type.

But you got to check your down light's voltage. some have built-in regulator(able to work with AC 220v-240v local) , some don't have built-in regulator(able to work with DC voltage only)

[lenkohe]

Okok... Thanks
Can I said that if it is 12v light I can Just use the 12v fan adapter rite...

[sacy]

not really. the current out put of your adapter got to be in check also.

if you use a 1.8amp current out put adapter. And this will cause the led to get very bright and slowly burn-out. (over-drive)

unless the down light have current limiting circuit built-in, if not the led from the down light will just draw(eat) what ever amount of current the adapter can supply them.

[lenkohe]

Ha Sacy, can advice please...
I had bought the led down hang type which use 12v
Can I use the following adapter to connect, does it have + or - for the cable connection.... the adapter is the used cooling fan, the fan spoilt Liao ..

[sacy]

What is your down light current rating?

If it is around 360mA. Then should be ok

Oops... I don't no leh
The shop uncle told me it use 12v only... Well it is cheap I get it at $12 where I saw it at mustafa selling $49 ...

Will it be ok to use the adapter.... I saw the x-fan also stated 11v leh...

[lenkohe]

Mistake is 12v for the existing fan....

Well I will try it, the most it will trip only... Haha... Hope not explode...

Nice work bro. Do insulate the exposed lead area to prevent short circuit.
