Question: does it work while plugged into the car charger or works with battery?
Document: Powerful when it works, but heavy and cumbersone compared to LED flashlights. however the big flaw is the trigger switch & or circuit board which failed after a few uses; also the car charger which should work even without the battery does not (possibly related to the switch mechanism). Batteries are fine; bulb is fine. Brinkmann would have a technician look at it if I pay to ship it or bring it in.
BTW don't hook it up to a car battery charger either, the high amps will fry it too.
got this for my dad, and the battery died after a few uses. so i took out a volt meter and started snooping around. I plugged in the wall charger and found that it was putting out around 25 volts... there is a 12 volt 2.8Ah battery inside, so the maximum the charger should put out to safely charge the battery is not more than 15 volts.... the charger fried the battery after only a couple of uses.
I have had many spot lights. This one has great light. I love the way you charge the battery out of the light. I will buy another battery so I can use 1 and charge 1. Comes with the car charger and house charger at a great price.The trigger switch is perfect and the safety switch is a slide and not the push in kind. It is much better.
Greetings,We own 3 of those spots. We had no problem.One we bought one year and half ago, the second we bought one year ago and the third we bought two months ago.This spot will light up a coyoye at 3/4 mile and light up his eyes at 4 miles.It is an heavy spot because of the battery. When new, the spot will last about 12 minutes before weakening. It is very good.It comes with a car charger and an outlet charger.
you have to have it It works flawlessly Best for bright light when you need it. I have two of them One for the car and one for the house
I bought 2 of these in the past 10 years and they both performed great...my third I bought in October, 2012 and last week I tried to use it and it was barely on. Plugged in the charger and the little red light would not come on...left it over night and still nothing, but if I plug it into charger and try it I get that same tiny glow.
Overall product is great but the car charger shipped with this product that is advertised as included is definitely not for this spotlight! !Not too big of a flaw to cause one to return the item but definitely annoying!!!! !
I use this light for light painting photography, It works great ! I do however think the battery life is a bit short, but i often think it may be a wise investment to just purchase another pack being as i use it differently then its average user.
Received it quickly and it works like a champ. In fact, it is brighter than a 10 million candle power spotlight I bought at PeP Boys. What is really good about it is you can leave the cord hooked up  all the time without worrying about overcharging it. That's what happened to the one I bought at PeP Boys, I left the cord on too long  and something happened to the battery. Now it only works in the cigarette lighter. I sold it in a garage sale for 5 bucks.
Answer: yes
