Yeah - it looks like you bought cream ones instead of white, but at least they're probably brighter than black. 
Maybe they are not rated as bright as the torched you are comparing to.
Otherwise, do you have the correct resistance value? They are probably 20mA as opposed to the really bright torches that use squarish LEDs (Cree) which take more than 20mA.
