I've heard that the Pelican Light Shield is the best. I've also heard that the wormlight is good. Please, let's put an end to the argument about which is best by stating the pro's and con's of the different lights. Thank You.

Not really a matter of pros and cons. The Pelican Light Shield Advance is a very well-built light (the best) with an absolutely crappy bulb. Mod it and it's the best of both worlds, and I've tried quite a few. Castlevania is bright and cheery now.

I've tried the wormlight. It's just not enough light with the new screen and decreased voltage.

A few months ago, I think EGM rated the wormlight one of the best GBA lights. If that's true (which I doubt), the other lights must be total crap. I have the wormlight, and it doesn't work that well for Castlevania. It lights up the screen a little, but not enough to see everything. Plus, it creates a nasty reflection of the bulb itself that you're constantly trying to see around. For me, the best option is just to play near a table lamp.
