I have some news on emitter swaps.
I talked to Richard at Mountain Electronics (RMM on these forums and a sponsor here) and told him there might be more than a few guys with GT’S interested in swapping to a cooler tint. He says that if you send in your stock mcpcb to him and buy one of his new XHP35-HI emitters, he will reflow it for free! He has 2 choices right now, 5,000k and 5700k tint. They are both the same D4 brightness bin as the stock GT 4000k emitter.
The cost of both are under $8, plus the shipping cost there and back. I’m in Texas and shipping a small package from him is usually $2 to $3. So I would estimate the entire cost at under $15.
From his store:
Here is the link to the 5000k.
Here is the link to the 5700k.
If your outside of the USA, then I’m not sure what shipping would be or if he even does international shipping. You’d have to contact him for details.
