ARC MH's from Aquaria Canada ?

Has anyone used these bulbs? Are they any better than the SA's ? My SA 10000K are really yellow.

I have a 20000K Arc bulb. It is too blue and lifeless for my tastes.

i just got the 20ks, they're too "dark" so to say...they look like i've just got actinics on, mind you they're only a few days old.

I had the 10k, it was way to yellow for me. I now have the 14K which I like more but they are bluish. I might add a PC 10k or something to balance it out a bit more.

I just ordered two 250watt 14k bulbs from Aquaria.ca, should arrive within the next couple of days. I'll let you know. Good deal none the less!

the 175w 14k's ive got are very blue, more so than the 50/50 pc's we're running on another tank. But it does light up the green shrooms and orange/red zoo's about 10 times better than the pcs

they're about perfect for my taste, but, it is very blue. id hate to see the 20k's

I have one problem.. maybe someone who knows electrical can chime in.. I have my MH on a digital timer.. If the timer is used the MH does not fire. I have to unplug the ballast and plug it in while the plug is hot (with power) for it to fire.. Any clues as to how to fix this?

If my explination sucks let me know and I will try to re word it ...

TIA!!

Hmm, that's strange. Try a mechanical timer. Some of the newer digital ones use a solid state relay, which could be defective.

Sorry Chad I cant help you. My ballasts fire on my timer...

as for the bulbs, I ordered a few 400w 14k bulbs for my future growout tank - they fire each and every time no problem ( I was having problems with the Ushios firing). But they are bluer then the pics of the 20k radiums I've seen online....

They are bluer then just my actinics.... Oh well! Sooo cheap

I wonder if they are marked wrong

. My 20000K is blue, but not overwhelmingly so. Certainly not as blue as just actinic PC's. I will probably keep it, and some day in the future supplement it with a daylight T5.
