I am currently using a 14K bulb from that Ebay seller... it's a 70W and I like it but have no basis for comparison. It seems to run a crisp white with a little blue using an Advance magnetic ballast, fired up really blue the first week or so and whiter now. My Paly frag has gained some color in the 3 weeks I've had it, so I suspect it's doing alright in the PAR area. The bulb was made by a company called 'Artemis Lighting', but as was mentioned before the problem with the Chinese bulbs is consistency... the next time I order a bulb I may get one made by a different company.
I do find that I need to 'warm up' the color temperature of pictures I take, so it can't be yellowish in the least... I suspect that 14K bulbs should be a bright white with a slight blue tint?
