My 100 watt burned out yesterday . tried calling them and they tell you you e-mail them AND GIVE YOU A VOICE RECORDING LECTURING YOU ON NOT FILLING THIER VOICE BOX . I have not recived my june 7th ordered or recieved a refund either . BEST BULBS OR NOT, ( ???? ) THIER CUSTOMER SREVICE IS BAD AND THE WORST I HAVE EVER SEEN . If i have to pay on cent to return this bulb , i will not bother . I am not sure i will reiceve a new one after paying the frieght .
