So it makes sense to reduce voltage on these strings. You also mentioned you have to worry about voltage drop.
I have the 100 count 2811 TC strings and it was already determined previously injection was needed. It would
be interesting for someone to determine how much injection is needed at some specified lower voltage level.
In the mean time I have been using 50% intensity and trying to avoid all white. I had one bad node yesterday
out of 1600 run over a few days along with my burn-in time previously. Now I avoid using any white at all.
Any comments on here on performing injection and lowering voltage versus lowered intensity.
Here is what is know
1) The heat generated by components in these nodes is generating heat and killing itself.
2) Lower power consumption by these components will reduce the heat.
not rocket science but those are the know facts
So how do we reduce heat
1) we turn down how hard we drive these RGBs (I looked at 50% last night and it is very acceptable, so my target is to reduce everything from 100% to 50%)
2) If we use a lower voltage instead of 12 volts it should have less power to deal with for each node. We know there is a 5 voltage regulator on each circuit board. From this point on I start guessing but my guess is we need to give each node about 6 volts so the node still functions. I'm not sure how much voltage drop we will see as we go further down the string of RGBs but from my point of view about 90% of my megatree is junk so if I made it a handful of node that progress (sad but true).
So here is what I'm going to try
1) I'm using LSP and have method for reducing my sequences from 100% to 50%. The method is not working completely yet but that is goal #1
2) I need to come up with a lower voltage to run these strings on. My current power supplies are not adjustable so I'm still looking for something in the 6-9 volt range.
So that is my current path to fixing this problem (more like a bunch of dead end roads).
