G12 versus double ended HQI Metal Halides

[Stat]

Stats 90 gallon 48 inch reef tank with some polyps and xanthia in it. I want to be able to grow what ever i want.

I am currently looking at upgrading my lighting system when taxes come back. I could use some informed opinions on the following lights or I will listen to your alternatives. My main concern is the difference between the G12 and the double ended Metal Halides please let me know what ya think.

I would think the difference would be availability of G12 bulbs. I don't think there is anywhere near the choice of colors or manufacturers like there is for DE bulbs. I also never saw any PAR studies done on G12 bulbs, so I have no idea if they are good or bad.

Well I dont have a LFS in my area that carry's MH bulbs anyway so if i have a Blown bulb unexpectedly I would either have to order one off line or dirve 1 hour 30 mins to get one.

Are G12's new to the field ? Do you think Long term I might have a problem getting replacement g12's ? they seem much cheaper to replace than the double ended ones about 50% the price according to Dr Fosters and smith.


I want to do this right this is going to be a major investment for me.

I would stick to standard double ended (DE) or mogul base single ended (SE) bulbs. You have a huge selection of colors, manufacturers and distributors for them.
