400w mh bulb

[wizardx322]

what is a good 400w mh bulb for growth and color?

i've heard 20k radiums give best of both worlds.
i've used the cheap plusrite 20k but i want alittle more blue.

i've used 12k reeflux when i had 250w and was thinking of getting the 400w 12k reeflux.

lmk know what yall think and what bulb yall recommend.

XM, AquaConnect, and Radium are all very popular 400w MH bulbs. Are you experiencing grow or color issue with your current lighting setup?

I'm currently using Ushio 400w 14k's supplemented with vho's. I like the colors and growth. I had 10k's and after that the radiums. 10k's grow stuff like crazy but you have to really like the whiter look. 20k's grow slowww and have a nice blue with no actinic sups needed. 14k's are a nice middle ground.

I'm currently running two 12k Reeflux and two 20k Radiums.
I've been a Radium guy for many years now and I honestly have to say that
I am liking the 12k Reeflux better right now. I tried one out few bulb changes ago and liked the colors my corals were getting under it. So this last bulb change I got two.

I run a mix of 20 k lamps along with ushio 10 K's. After the ushios burn in they loose a lot of the yellow tint and the 20 ks help to bring out that extra blue. I like some of the colors that develop when the corals are exposed to the 20 k lights but i need the ushios to actually see the color. Otherwise everything has a blue tint and the reds are washed out. Underneath the mix my reds are deep and my blues and purple s really develop as well.

I'm running 2 400watt Radiums right now and next bulb change i will go with 12k reeflux. My friend ran 12k before taking down his tank and I loved the color. You really can't go wrong with either bulb
