yup they are.. that actualy shows that the color should be better with the nipple down (this is PAR output only as color was almost identical) so we should do the oposit of what Venkiw asked, BUT this is also assuming that you do not use a reflector, sence I have tested 6 different bulbs this way my self I can tell you that when you use a reflector of good quality there is virtualy no difference.


Bob, do you mean that your bulb are hanging up and down so that the screw part is up? if so you should try them horazontaly as these bulbs are not made for verticle use and this could be the source of your yellow on the AB's.
