LED pars
I have been looking at some of the cheapo LED pars, and a couple of the ones I have looked at seem to flicker when slowly dimming up and down. It seems as though they are not using 256 steps of control for the LEDs but maybe only 32 or 64. Has anyone else noticed this?

Re: LED pars
Such is the nature of cheap LED pars.

Re: LED pars
I have used the Irradiant cans. There will always be steppy dimming and a falloff at the end of the dimming curve. This is generally the case of all low-price cans.

Re: LED pars
I use the Showtec LED pars (£30 ea.) and they're fine i mean on any LED par in this price range you're going to get drops at the end but if you don't want to pay £300 a fixture then you have to learn to live with it

Re: LED pars
My LED PARs (36 3W LEDs, $549 ea) and 252 wash fixtures (252 10mm LEDs, $218 ea) dim just fine with no flicker.

Re: LED pars
The new Vivid II I posted about last week offers a smooth dimming curve and is a direct replacement for the ColorBlast Powercore.

Re: LED pars
I've seen this Vivid II fixture added to several smaller regional rental inventories, and would really love to get my paws on one to try out. For the price, it looks like a killer fixture. I really like the form factor established by Color Kinetics, as much as I dislike the CK power supply deal.

Re: LED pars
Many of the 4 channel leds have the dimmer channel like this,from 0 to150 = dimmer, and from 151 to 255 it strobes at different rates. This may be why you see flickering when dimming from 255 to 0.
Try not going beyond 150 if you want no flickering or strobing effect. Ed Last edited by edwardmw; February 20th, 2009 at 12:53 AM.. Reason: spelling
