Led Driver Or Bad Pot?

[noobwithatank]

I currently have a pair of maxwellen drivers which are running 15 leds each. I have 10k pots installed from dimmer. Every so often the leds will flicker/go out quickly. If I catch it in the act playing with the pot (turning it either direction) solves the problem. Would the pot be prone to going or would it be the driver which I know isn't the best.

Could be a loose wire. .. could be a thermal thing. .. you have fans on your heat sink? What are you using for a heat sink? What are you running the leds at?

Heat sink is 16inchs by 8inchs. I have 2 fans 120mm on it. It is a proper heat sink with fins every half inch at roughly 3/4 height. I have checked the connections and even switched pots between the 2 drivers and still the same thing. I am thinking of buying new pots to test as it is the cheaper route then buying new drivers. Leds are running at 650ma

15 led 3.5Volt on each. Means your driver should do about 70Volt.
That's hard to believe - check the specification from your driver.

I would short a couple of LEDs and watch if it help.

 

[noobwithatank]

you mean short them out? I don't see how that will help..lol

What LED's are you running? That driver has a really low mA rating. There is a good possibility it is the pod. I had some replaced in the past. They were good and cost me $6 or something for a bunch shipped.

The leds in question are bridge lux. Now here is a new one. If I decide to order a new pot. Should I order 10k ?

But which LED's did you select? Different colors require different mA.

Oh wait. I think bridgelux all have a max of 700mA. So you should be good there.
