View Full Version : Anyone use XM 15k double ended halides

I just purchased 2 XM 15,000 kelvin 150 watt double ended HQI bulbs to replace the bulbs in my lighting fixture. Has anyone used these? I find the light to be very yellow and not to have much of a bluish white tint to it. I was using 14k Ushio Blue bulbs before these and they had a much bluer look.

I am guessing the bulbs may need some run time before they hit their true spectrum though if they don't get any whiter then this I think they should be returned for a refund. I would expect better color from a 6500k bulb.

I'm using the 250watt DE 15,000K XM bulbs... and after they burned in, they have a nice blue tint (not too much though). I'm running them on Lumatek ballasts in case that changes things...

I'm using 400 watt single ended xm 15ks. The start out a bit yellow then burn in to a nice blue. Are they 15k? doubtful. 12.5-13k if you ask me. Still nice par and nice k if you like the look.

I hated my XM's. I used Pheonix and loved the color.
