As always my 2 cents.
Like going to Home Depot, and seeing 40w, 60w, and 100w bulbs.
LEDs come in a large range of brightness.
Add in now lens, and direction. None, shoots light straight up, Frosted, diffuses to a fuzzy ball glow, Op-Max over 300 degrees and 3x as bright.
These are all personal choices, and some of those have been mentioned here.
How is the room lit?
How is playing, how old or how are their eyes?
Height or angle of the player....where a single LED can ruin your line of sight.
Games like WH20 were pretty damn well designed for most of its light placement, other then perhaps the boulders.
So Incandescent happens to look pretty good, IMO on this game.
Correctly done LEDs will look nice too.
James posted a beautiful picture of his, Excellent Job, my friend! I believe would be done with all 1 SMD 5050 bulbs.
For anothers, this is too much.
For me personally, I blend everything. I dont think I have but 1 game that has all the same bulbs in all the sockets.
I know thats a PITA for most all, but for me, its like my home. Every Lamp and light is not lit with 100 Watt bulbs.
I like some mood and darkness....some mystery behind the caves.
Yet, I see the other side, light it all up and see everything bright and even.
I dont think a consensus will ever be reached, because of our personal differences, but knowing the options that one can do, is
at least the best way to not "do it wrong"
