Anyone use an XM DE 150 watt 15k or 20k ?

[All Delight]

I have a 150 watt sunpod. I changed out the 14k it came with, put in a helios 20k.

But I like my friends 250 xm 20k single ended bulb.

So, I'm debating on trying either the 15k or 20k de for my sunpod, over my jbj 24 gallon.

Anyone else try this?

everything I've read and heard says that the XM 15ks are bad bulbs with VERY SHORT life spans. Their 10k and 20k though are very good.

like above, everything i've read says that 15K's have the worst PAR and lifespan of all the bulbs.
