Sorry guys, yes there is a lot of great info on this topic in the forums, it is what inspired me to look at this mod. What is frustrating is that there does not seem to be (as near as I can tell) a way to match an Incandescent to an equal powered LED so you end up with the same Lumens/Lux you had before. I was hoping someone had some input on what size LED bulbs you used and if they were same/more/less light vs the originals.
As near as I can tell (and this is partly guesswork):
1) warm white is about 10% darker than standard white and is more natural looking
2) 42 LED's would be brighter than a standard t10 921 bulb (not sure by how much)
3) 20-30 LED would be close to the same Lumens as near as I can tell
