I wanted an LED replacement for the 20W T3/G4 halogen capsule bulb I had been using in a desk lamp. This is near-perfect in terms of light output. Yes, that means the brightness is closer to that of a 20W halogen rather than the advertised 30W, but that's fine with me. Color temperature (claimed to be 3000K) is very close to the halogen, as well.With ten of these in the package and a 12-month warranty, I should be set for a while. I'll update if there are any reliability issues.
