Why doesn't light source doesn't work even with brand new AAA batteries installed the correct way?

Because the battery holder is also poor quality. Last one I bought I had to exchange the LED unit from the one before that broke. Have a play around with the springs and contacts.

I bought two units and have had no issues. I'd send it back for a replacement.

2 things you have to check when installing batteries :1) make sure the the spring makes contact the NEGATiVE ( flat part ) of the battery when inserting. 2) make sure the battery holder goes into the flashlight the correct way. Usually the end of the battery holder marked with "+" or with the bump on the end goes in first .Good luck !!!

Hello Dear,You can apply a battries and it will work. Close the light and keep it in any corner and it will give you a light.Hope this help you.Regards,

First make sure at least 2 contacts are making contact. Note that although there are several + contacts, they are all connected. Also go by the lights. Batteries sent are fully charged, so use a used one.

It is possible that your light requires a constant "current" source (since you mentioned 32-36V), instead of a constant "voltage" source. This is a constant voltage source, 12VDC.

i did same thing at first, & was sure I installed battery right. In frustration, I flipped battery opposite direction inside flashlight & it worked fine. It stil seems backwards to me, but I LOVE, LOVE, LOVE this flashlight! If yours still won't work after installing battery in all directions, then it must be a defect. Hope it works for you. It's the best flashlight I've used!

Yes. Standard AAA batteries will not work. Had I known this would not have bought the light.

If the 18650 batteries are charged, then there might be a problem with the switch or the the connection between the batteries and springs, or the spring and the LED. You might have to pop the thumb switch cover off and try making the connection manually to test it.

Yes. Once you get the light, wipe the threads were end cap screws on.. Very important? Charge batteries as indicated. Positive end first for both batteries. The full light beam setting is only for short use as it will dramatically reduce battery life.

After installing make sure both screws are tightened in good . Then the cover has to be on and the screw holding cover has to be all the way tight.If that does not get it the new lamp may be defective.

It must be defective or you didn't turn on the switch that turns on the lights. The switch is on the underside of the disk in the middle. Maybe the batteries aren't good. Check for that too! But, you do have to turn on the lights for it to have lights.

My light did the same thing. I unscrewed the head with the LEDs from the body where the batteries are. I was checking for lose or burnt pieces. After I put it back together it started working and has worked fine ever since. I believe the lights worst problem is little to no quality control at the manufacturer.

Remove the screws on the back and insert a new battery (or both). The replacement batteries don't seem to last quite as long as the originals, but the light will once again come on.

You have to make sure you insert the battery upside down until it connects or else it won't work. The battery should automatically work and the light should turn on immediately.

Try that clear battery sleeve. I haven't used aaa battery's in mine yet. I ordered extra 3.7. them large batteries. For maximum light output

Sounds like a defect, I would contact somebody and get a new one. Hopefully they'll take care of you because this is a great light. I ordered mine months ago and carry it with me everywhere and it works like a champ! I haven't had to change the batteries yet either!

As someone else mentioned in the battery test mode the Green (good), yellow (questionable/low) and red (bad) LED won't work, as those are meant for primary Standard primary batteries (AAA, AA, 9volt D and the like). I would just use the DC Voltage setting to test batteries other than standard primary batteries.
