So recently I've started to notice in most of my beta packs. I tend to use pre-heat on all the channels and recently the intensity of the pre-heat seems to be increasing, theres a difference between Beta packs and channels. The pre-heat intensity always is the same between outputs 1 & 2, 3 & 4, 5 & 6. 
  
I have 9 beta packs in total all with similar serial codes 8 out of the 9 have issues and it wouldn't surprise me if the other one started to develop similar issues. I have posted below each of the beta packs serial numbers and faults.

It seems to be the pre-heat level seems to creep up slowly. So at the start it was hardly noticeable but over time (a few months) the preheat gets brighter and brighter. All of these results are using the same light, same power output (they are portable not install) and were reset before doing this list. 
  
I have a feeling from reading other posts that this is todo with the transformer or power board and a batch of faulty components however I wasn't sure so thought I should ask and see if anyone knows which serial numbers are affected.
