> First, a arithmetic error: it's $0.74 per CFL, not $1.74. So so the LED costs 17x as much as the CFL.
Sorry, what? The linked four pack of CFLs costs $6.97. You must have been doing some very interesting taxes this week if you think 6.97 / 4 = 0.74. (Apologies if you are not American.)

They don't exist. Even cheap direct-from-China LED bulbs* are more expensive than that. $10-$15 per bulb is the typical cost and you'll be hard pressed to find 800 lumen (60 watt equivalents) for any less. I'll gladly check their efficiency if you can show me where to get that many lumens for that price.
That is very very interesting, for me the price is listed as $2.97. I can post a screenshot if you like.
I'm wondering if it might be because there are utility rebates in my area, and my local store has a lower price.
> They don't exist.
I figured. I don't think the time for LED replacement bulbs has come yet, but we're getting there.
Although I am considering this fixture http://www.ebay.com/itm/170922117326 for a new installation because once I include the costs of the hardware the price is a wash, and LEDs are much better for outdoor use.
I do hope they are not lying about the lumens though.
I think LED specific fixtures are going to be a much better choice for now, rather than edison base bulbs.

* Actual lumens. Many Chinese reseller sites will outright lie and you need to check the manufacture's website. Eg, http://dx.com/p/193927 says 1008 lumens while http://www.sencart.net/e27-24smd-5060-led-pure-white-lights-... says 700 lumens.
