Replacing Bulbs

[heath]

I think that its getting close to replacing the bulbs on my light, it is a T5 Quad HO. presently there is 2 blue coral plus, 1 purple coral plus and 1 white.
It is a used light and I am not sure how long they have been in the fixture..
Is there a sequence for replacing them. I don't think that doing all of them at the same time is a good idea I would be afraid of shocking or burning the corals in the tank..
thanks for all your suggestions and where is a good place to buy from, they are 48"

Hi Heather any thing I've read sais to do them one at a time.

That's what I have heard too, wonder if there is a sequence, like the blue first and the whites last..

Incredible aquarium sells them at the usual prices. Also if I remember correctly beanbagfrags.com (unibob) sells them too

you can either change a few over a period of time or just shorten your photo period with new bulbs over a few months until your back to your regular schedule, hope that helps

thanks for all of your advise..

Color sequence doesnt matter just do them one a time or shorten the light period like others have mentioned.
