A 13W CFL is equivalent to a 60W regular incandescent bulb. It uses less energy, and helps protect the environment. Depending on your kWh rate, you will enjoy significant dollar savings per bulb!
Globe Ultra Mini cool white compact fluorescent light bulbs simulate daylight making them ideal for offices, reading areas, kitchens, and workshops.
Globe's Ultra Mini size fits most fixtures that require a standard medium base regular incandescent bulb.
The lifespan of one Globe Enersaver® bulb is 8,000 - 10, 000 hours and will outlast 8-10 regular incandescent bulbs.
You can find comparable 13 watt CF bulbs at Home Depot for $4.88 / 4 pack. The Home Depot bulbs have a longer warranty. I bought both these bulbs and the Home Depot bulbs and can not tell a bit of difference in color, ramp-up time, etc. Save your money -- which you are probably aiming to do by shopping for items like this anyway.
Okay for the price, some annoying downsides:
Purchased the 4-pack for my 4-light bathroom vanity fixture. The compact design is a nice fit for any light as some of the full-sized CFLs can be too large (CFLs are generally bigger than incandescent bulbs). I've had problems fitting CFLs into some light fixtures, but these are actually a little smaller than normal incandescent bulbs. My biggest complaint is that the lights take about half a second to turn on after I flip the light switch. It was annoying at first, and it took some getting used to.... more info
not a good first experience:
This was my first experience with compact fluorescent bulbs. I ordered a four pack of the 23 watt bulbs and a four pack of the 13 watt bulbs. The 23 watt bulbs arrived first. They were thrown in a box with very little packaging. One of the bulbs had broken. This was a bit disturbing since they contain mercury. After doing some research, I learned that if you break a fluorescent bulb, the mercury is only hazardous within the first 15 minutes or so. This is because it is in a gas form and will soon disperse... more info
Harsh spectrum, slow initial illumination.:
These feel like the previous generation of CF lights. They take more than a second to turn on, and they flicker as they illuminate. They have a very wide spectrum output, but low lumen levels. The light creates very crisp shadows and a very artificial feeling light--not unlike older style florescent bulbs.
