New GE Daylight anyone?
 
Have to say I used to always buy Phillips or GE (last time about 2yrs ago); then upon move I started Bright effects; both daylights were well daylight coloration.

I just bought a new one yesterday from GE (since I nicely busted my other new one in a dull moment) the seem more like cool blue borderline purple to me then they used to? It sure sticks out in the tank specially becuase over the 45 I only have 2x18" tubes side by side not back to back across and the 2nd one is a soft white and that difference really looks like sunrise - sunset from one end of the tank to the next....

Just really wondering if they amended there spectrum since I last bought them or what? The Bright effects ones aren't that 'harsh' blue :-?

Is the bulb you just bought one you have not used for awhile since the last time? Maybe you are used to the other type that you have been using.

That GE I hadn't bought in a while no. But compared to my Daylights in the 55 it just seems bluer/ colder to me.... Or maybe its just my eyesight today.....That's why I needed to ask I guess...if its just me or the actual bulb.... :-)

It probably has a slightly different Kelvin rating. If it's the same as the other brand then someone is lying about their Kelvin. And it's not nice to lie about Kelvins.

:lol: It was a serious question from my end...really really....don't make me call you names now....

Mean Harri 02-05-2010 08:07 PM

Seriously. The 2 bulbs are probably slightly different. I doubt it's your eyes that are wrong. I had to throw in a little silliness at the end of my last post or it just wouldn't be me.

i have natural daylight T12s and natural sunlight t12s for my 110g, the daylights are definitely brighter and bluer than the sunlights, just to add :)

Angel079 02-08-2010 10:23 PM

Yea I have the sun-day mix in the 55g - Or better said I HAD till about 2hrs ago :-) Experimenting here again :-)
You wanna chime in with ideas read here http://www.tropicalfishkeeping.com/a...att-55g-36847/

So it sounds like the daylights are upwards of 6700k or higher if they are blue-ish. Sunlights must be lower. 5000k? I'd venture to say the daylights are probably the better bulb. I'd also listen to about half of what I say and regard the rest as lies. lol
