150 DE Lighting options (10, 20, 14.5, 13??)

If you're really not sure what you're after... Check ebay there are some sellers of some inexpensive HQI/mogul bulbs, at 10$ each its relatively cheap to try them out and see what temperature you (and your corals) prefer.

Theres a big long thread in RC's equipment forum "cheap ebay bulbs" or somesuch with some reviews / basic info.

Very interesting - only problem is they cover 175 and above, so nothing for the 150's - I do see there are some for 150, here:

if this works out, I may have the Seahorse get some in from J&L or HR - If the above one works, it's a great price (under 50 bucks) even if it only works for a few months - and then I can test out the 14k spectrum!

Now - the question is - will this work with the Aqualight Pro ballast?

My 150de (tar ballast nothing special) will fire 175 de bulbs; if you look in my frag sale post i've got a picture up with a cheap (think it cost me 5.83$ shipped) 175w 14k...

HMMM - well now, that is interesting. I wouldn't be risking damage to my ballst, would I?

Which place did you order that one from? wouldn't mind looking back there and grabbing one to check it out

Danke!

No idea on the ballast - mines been running for a fairly long time no problems.

Don't ask difficult questions lights64 was the seller - not seeing any true auctions anymore though...

Thought I'd revive this with a few qs - PAR, PAR, PAR. I'm really interested in hearing what brands produce equal PAR in higher K temps.

From what I've seen, there are some brands (Hamilton) whose PAR drops as the K temp goes up - but XM bulbs don't?

What are the thoughts on this one?

As a rule, PAR goes down as colour temp goes up from 6500K
