Sylvania incandescent 65w par30 bulb
This is your standard par30 incandescent "warm white" bulb. It gets hot to the touch when it's been on even just a couple of minutes, because it's so wasteful. But it's very dimmable, it turns on immediately, and it's got that yellow "warm" color to it that some people swear by.
Brightness directly below the bulb: 40 lux
4 feet to the side: 20 lux
8 feet to the side: 9 lux
Because the lighting element is actually deep in the bulb it doesn't cast light well to the sides.
Use this bulb as a "comp" to standard incandescent bulbs.
Price: around $2.50 per bulb. Lifetime: 750 hours.

GE 15w par30 "daylight" CFL
This is a standard compact fluorescent version of a par30 lightbulb -- essentially a "pig tail" CFL inside a par30 shell.
It has that fluorescent buzz and a pretty pale (or "cold") color temperature. It takes about 60 seconds to warm up to peak brightness, starting out dim. It often won't be dimmable (although you can buy dimmable ones, just look for those in particular). And it has mercury in it, so good luck recycling it or cleaning up after you break it. But it's comparable in efficiency and lower cost next to current LED bulbs.
Directly below the bulb: 36 lux
4 feet to the side: 25 lux
8 feet to the side: 14 lux
The CFL isn't quite as bright as the incandescent but it feels fairly comparable in brightness. It's slightly better in terms of light dispersion to the side. This is the current standard for efficient lighting, so it's a good comp for any LEDs you might be looking at.
Price: around $8 per bulb. Lifetime: 10,000 hours.
