I'm pretty sure there was another thread out there doing this, but just felt like I may as well share. I've been working on putting LEDs in all my games (I'm neutral on the look overall, but feel like reducing heat is worth it.) I figured it couldn't hurt to take some pictures of different types of bulbs in GI, and I had my Fish Tales opened up already, so thought I may as well use that. Hopefully this helps someone!
1. standard bulbs (left) vs. Cointaker warm white Retros (right)
2. Cointaker warm white Frosted (left) vs. Cointaker warm white Retros (right)
3. Cointaker cool white Supers (left) vs. Cointaker warm white Retros (right)
-Any LED is going to be brighter than a standard bulb.
-Retros and Frosted both seem to disperse light pretty well, and provide more light spread out over at least as great an area as standard.
-Retros and frosted are VERY similar in terms of amount of light and area of dispersement. Retros may be slightly brighter, but frosted are substantially less expensive.
-Supers seem to not throw light in as many directions; looking at the slingshot plastic, you can see dark areas where they don't illuminate very well.
-Largely personal preference, but GI (at least for games of this era) looks best in warm white.
My personal opinion:
Retro > Frosted > standard bulbs > Supers
Cost be damned, retro is the nicest, but Frosted is by far the best bang-for-the-buck.
