Quoted from YeOldPinPlayer:The flexible ones are good for places where the bulb placement doesn't light up what you want it to very well.
This is one area where I really like LED's. I used them to shine up at an angle against the carousel roto-targets (kind of like stage lights) on my KOD and to light up the ball return area on manual-load games (Nags, Heat Wave). Provides light where there really wasn't much before.
