First of all you guys are awesome for detailing such a nice DIY mod.

This thread caught my attention and I've already ordered my stuff. I noticed that the higher the wattage, the higher the lumens, so I ordered 4 of these 15 watt Blue LED MR11s

These were the highest output in MR style I could find.

I want to ask everyone a question who has done this.

Are you having any issues with the Resin yellowing from UV rays?

Any issues with the wire you chose? (Some appeared to use standard speaker wire)

Anything you would do differently next time?

Thanks everyone!
