XM or Ushio

Getting ready to order 20k lights for a lps-sps color-up tank anyone have pro-cons for XM or Ushio's?

i heard they XM's only have good par as a 10k bulb but then again, your just going to 'color up' your coral so i guess any 15k-20k bulb would do...

If you want the tank to look blue, get XM 20ks....they have more PAR than the 15ks.
The XM 10ks have a yellowish look to them.
What type of MH do you have....SE or DE?
If SE, I would go with either a Reeflux 10k (ice white color) or a Reeflux 12k (nice blue tint).

Decided to go with Aqualline AB 20k's....I have a buddy who has these bulbs and the tank looks awesome, colors are intense..

Incredible, only about 16 hours of burn-in time but I can really see a difference in colors, all the zoa's look brighter and the colors are more intense or neonish looking, can't wait for the bulb to burn-in. I've also noticed that it tends to make purples and blue's "pop"

Here are some pics of a red blasto that I've had for a while, with the other bulbs the green had faded and the purple was gone a long time ago. I can't wait for these bulbs to get totally burned in......
