Help choosing CF bulb

[clb2196]

I'm doing a DIy hood mod for my new tank using cfls. I want to have about 2..3ishWPG, since that's what my old tank had. It's 36 gallons, so I'm looking for about 80 watts. Would two of these bulbs work? It doesn't say what the color temp is.

Also, I'm confused about what wattage I want- the actual wattage it's using, in the above case, 40, or what it replaces, in the above one, 150 watts. If the latter, I would assume I'd need something like this.

Help?

try these bulbs from your local walmart. they work great and you can get them from 10 or 13 watts to 27 watts for the 100w replacements. remember ge daylight cfl!

oops... EDIT: actual wattage of bulbs... not what they replace.

Yeah, I've given up finding 40 watt daylight. Unless they have them in the store, online all anyone has is 40 watt soft white.

So I think I'll double everything up, do 4 20 watt bulbs instead. It'll spread out the light and heat better, too.

more bulbs at a lower wattage is better for cfl's anyway to spread the light more evenly.

walmart sells 40watt replacements in DAYLIGHT!

Well not online apparently, cause I couldn't find 'em. Did you see them in the store? I think I'll go with 4 bulbs anyway, but I'm curious.

ya, i got a 2 pack from there, they also sell some bulbs in the pets department, but i think you can get them cheaper in the lighting department.

this is what i was saying... http://www.walmart.com/catalog/product.do?product_id=5984218

they usually have 2 packs at my walmart. they go up to 27 watts (100 watt replacement)

Oh ok, but someone confirmed for me that what I really need is 40W actual, not replacement. The ones I need are 40W actual, something like 150W replacement, those are the ones I can't find in daylight.

nope 27, that's the best you get as far as i see. there are higher wattage cfl's but from my experiences they're not the same unless someone can recommend one i haven't tried. i think 4 20's (75 watt replacements) might be a little much though... idk? i am using a 10 and a 27 about 1 1/2', maybe 2' above my 30. anymore and i need co2 to keep algae at bay. might be different for you though. also i see you said in a hood i believe. that suggests to me you might need high light as some spots will be brighter than others otherwise and may just be algae magnets.
