Re: [RE-wrenches] mod waveform LED dimmer

2018-09-05 Thread jay 
HI Ray,

Yea thats a good assumption based on CFL’s.

But LED are different. 

What happens is that the LEDs will dim a small amount and then ( there are 4 
LED lights in a light fixture) one will turn off for a short while ( few 
seconds) then it’ll come back on and another will go off and on and on it goes.

I’ve see this on other systems from a generator with poor quality.

Its pretty odd and totally random.

The options for this customer are going back to incandescent, or maybe there is 
a  LED/Dimmer combo out there that works. And as to trying out others, yea 
thought of that but they are expensive and could be a big rabbit hole.  

thanks
jay

If a regular dimmer doesn't work, which because of the sharp edges I 
would not expect to work very well,


you could try a variac.

HI All,

I’m asking the group for a very obscure piece of information.

I have someone with an very old Trace 2012 mod wave form inverter and wants to 
use their new LED bulbs with a dimmer

Does anyone know of any LED/dimmer combos that will work?

thanks in advance

Sorry I can't help with specific models, but my guess is that most 
dimmers will work.  They will probably buzz annoyingly due to the mod 
sine, and probably die a relatively earlier death from the extra heat.  
That being said they could last several years, and reduce total load.  
Let us know what you find out.  I'd probably just grab a couple from the 
local supply and play with them.  I do quite a bit of Mad scientist work 
here.
