I have had this DEFT FTP since last year and it just absolutely blows your mind!! As im sure you all know. Anyways recently the light has just turned from a monster thrower with a bright spotlight to a yellowish tint that is very weak. i put in fresh lithium AA's but still the same result. It's quite sad that i can't make a white laser beam into the sky anymore. Any suggestions or reasons why it has become this color? Any fixes.. i miss it
