This could sound like a strange question but it could same me a lot of money on bulbs!

I bought a cheap 3x24w luminaire ages ago on eBay, but I think the bulbs were crap as they all died quite quickly one after the other. As it was cheap, I need to know if it is a standard size or just some knock off that won't fit the sizes of the standard T5 bulbs, like the 22" Arcadia.

Question: Is the 22" measured from the pins or the actual bulb? :?

Oh and while I'm asking, does anyone know the Kelvin rating of that Arcadia bulb? ^^ I usually find the plant pro thingy's to make the tank look waaay too pink :wideyed:

Cheers,

Tom

They sound like standad 24w t5HO bulbs.
As such you can save even more cash by buying bulbs from lampspecs. See james's thread on cheap t5 bulbs. All the bulbs James reviewed are available for 24w. Think i replaced all 4 bulbs for around £20 - 2 daylight + 2 grolux.

No idea on details of arcadia bulbs.

All plant gro lamps make the tank look pink. Most people use a mix of these with a daylight which balances the colour out.

daylight on its own tends to look greenish. Therefore try 2 pinks with 1 daylight or 1 pink and 2 daylight then choose the preferred combo.
