Is it wired up with anything else in the supply circuit? do you have multiple LEDs wired together in the same loop?

Also, do you have any current (amps) and voltage ratings for the LED? You might also find a spec for the angle of the LED 'light cone', also known as the 'viewing angle'. Many LEDs have quite a narrow cone, eg. 30 degrees, which means the light shines from the LED at up to 15 degree angle from each side of 'straight ahead'. The impact is that for LEDs with a narrow light cone, they only look at their brightest when viewed head-on. In such cases, because they do not disperse light very well to the sides, you may not achieve the effect of a fully filled reflector like you want. But a correctly wired LED should be bright enough to achieve something very close to it by the time the light has refracted through the clear lens...and having said that, your LED does look really dim in the photo.

Photos of the setup and info on power supply/ LED specs might help solve the problem....

I tried on a hobbyking led kit, then a modified servo
about the pic I wired the LED with two 1.5Volt batteries
but about you talk about this I'll try with diffused light LED for the angle
there are the LED specs
