First is the Dual Xenon Marine Rechargeable Spotlight. This is a pretty small spotlight and some might even still have it in the xenon rechargeable flashlight category. It only weighs three pounds and has a pistol grip style handle. It can be recharged either by a wall charger or it includes a plug for your cars cigarette lighter for charging on the go. It has a one and a half hour battery life which the company claims is the best in the industry. I haven't seen sufficient data to prove otherwise so I won't argue with them. It has 2 bulbs and you can have it set to have one or two on which makes changing brightness a breeze. You can also lock the trigger so you don't always have to hold it down.
If you are in need of something a lot bigger there is the Sunforce HID Rechargeable Spotlight. This thing looks completely ridiculous. The first thing that jumps out to me about is the fact that it advertises that it can provide up to 25 million candlepower. I have no idea what you could possibly need a light that bright for but it sounds bloody awesome. I want one. Its a lot bigger than the previously mentioned light, it weighs a little over eight pounds. The lens apparently has a similar diameter to a soccer ball. It has 2 plastic stands that fold up for for easy transport and and has a large handle on the top so you can carry it like its a toolbox or suitcase. One one charge it can last up to 55 minutes which sounds like quite a lot to me, considering how much power it must eat up. Some of the amazon reviews of this product say that it appears to only put out ten to fifteen million candlepower. The spotlight may not be as good as advertised or this person may have gotten a lemon, I'm really not quite sure.
