converting plug in lamp to battery

hello I have a little accent lamp which uses a 0.5w LED night light bulb. If I wanted to power it with a 2000mah AAA battery instead of the current plug-in how long would the battery last before recharge?

The LED would require closer to 3vDC to operate normally. You may be able to run it on two AAA batteries in series. Two AAA would last a long time between charges if the light was only used at night. Probably a month.... maybe more.

I would think so. You could try it on standard batteries first.
Keep in mind that regular batteries are 1.5v and rechargeables are 1.2v.

If using a disposable battery you can run it down to completely dead. If using rechargeable batteries you will not be able to use the full capacity listed on the battery. I would use regular alkaline batteries and just toss them when dead.
