Hello (sorry I'm a lil cory-egg delayed this AM lol)
Here's a picture of my 10g hood for ya; filled with 2 daylight bulbs @ 6500K from 'Bright effects'.
Really any home store will do and any size bulb that fits your socket in your hood; mostly they're called Daylight
or Ultimate Daylight
, come from companies like Phillips, GE, Salvina, Bright Effets.....
What you wanna have on the compact fluorescent is some who's wattage equal about 1wpg
; anything labeled daylight (which is a full spectrum) and read the small print for Kelvin rating, ideally 5-6500K
for fish & plants.
I get all mine, big & small at Lowes, but the availability apparently varies from State to state so I donno what's available to you. Price are (for the small one's seen below) for a 2 pack $3 and for the 2-pack 4ft florescent for me ~$5-6
Hope this helps
