LED fade problem

[Kim]

Hi,

My LED strings is fully lit at 60% in LOR2.

This makes fades look to fast.

Is there any way to configure LOR2 or a controller that 100% is 60% to get a more linear fade?

The best way to do this will be to change your fade to end at 60% rather than 100%

Kim, are you sure about that? It sounds very unusual. I have a huge variety of LEDs and I've never seen full brightness at anything under 90%.

Just for giggles, why don't you put some sort of incandescent light bulb on on the same channel for testing purposes and then see if the LEDs are still bright at 60%. If so, then I guess you have to use Dan's suggestion, which is a good one.

I am betting that Richard's suggestion will solve your problem. On some of my strings the lights would even seem to get brighter and then drop off suddenly when trying to fade. It depends on the length of the string and the brand. I solved the problem permanently by building terminators and plugging one into each channel.

Thanks Breaker. Lot's of people have trouble with fading leds as you mention.

With all due respect to CrazyLady's approach, I think it is VERY time consuming and is a dangerous approach that can lead to electrical shock if you are not careful. I posted some photos and instuctions on my site for another menthod. I bought 39K 1/2 watt resisters at Radio Shack, and then bought some "clam shell" plugs at Home Depot. You simply attach the resister to screw terminals inside the clam shell and snap it shut. Total time is about 3 mintues to make and the cost is about 80 cents each. I suggest you not mess around with making things like this by hand.

Thanks for your info,

I tried once more last night with 8 100ct LED strings (arch) outside in the dark and it seems the strings is fully lit at 80%. Fades look fine when using normal arch sweep sequences.

That's what LED's will do. That is normal, you will not see much change after 70-80%.

You might also check your 1/2 intensity level, had to drop mine to 20% for back ground effects to look right on my arches. Fade up and down levels can also be changed using S2 using the Fade Tool.
