Quoted from lordloss:

The current level of illumination was designed this way on purpose. If JJP really wanted to change this, they would. The end user might not like how it turned out, so this is where the kit comes in.

Quoted from DaveH:

When Hobbit comes out with a different system we will call it learning from you're mistakes. I always assumed that was what good manufacturers did. When you design the next version of something, you try to fix anything you did wrong the last time. Sometimes that can't happen because of costs, or unrealistic expectations. But in this case, they would be foolish to not change it. Heck, I've been a supporter of JJP and will be happy to admit they missed with the GI design because there are lights over my game adding more light. But it isn't as big a deal as people make it out to be. Add lights to the game, add lights over the game, whichever you prefer. Job done.
