if i get this product for my flashlight and it charges over three volts how can i prevent it from blowing a bulb.

No matter how long you charge it it will not go over safe limits to hurt anything.

depends on your flashlight. does it have an actual bulb or an LED? these batteries are safe for every cr123 LED flashlight that i have ever owned. if your flashlight has a high pressure xenon bulb or similar then you need to check the specs. dont bother with charging voltage, you are looking at discharge voltage. what kind of flashlight do you own?

It's gonna charge To its max with a green indicator letting you know its complete. Will not blow the bulb

Make sure the bulb can handle at least 3 volts, its a 3 volt battery max. .

Perhaps your charger is bad...Not real sure. Mine still lights up the entire neighborhood. Sorry

There should not be any plastic on the bulb when you plug it in, any plastic that comes around the bulb should be removed before powering up. Mine came with flexible foam around the bulb to keep it from knocking the hood, which I removed before plugging it in. There was nothing else on the bulb that could have melted.

They don't have light bulbs, they have a single l.e.d. Possible that your battery pack is in backward or that the springs inside are just not making a good connection and they need to be stretched out a bit. I own three of these flashlights and they are great quality and work great so I'm sure the fix has got to be something simple...:

Seven and a quarter volts will damage the LED system in a three volt flashlight. When in doubt ask Maglite.

I have always had moisture problems with the flashlights. I remove to top, and store both parts of the light in a sock.

Fusr blowing us not due to the battery, what u have the fuse protection is drawing more than 10 amps causing the fuse to blow. Is polarity correct? Is the hot lead (red) making contact with ground? Good luck.

This flashlight uses only one AA battery which puts out 1.5 volts. 18650 batteries put out over double that so the bulb may not last very long. With one AA battery in this light it is extremely bright so I would stick with just the AA.

If you are using a dimmer switch, there may be some electrical current leaking through the dimmer switch circuit. If you're using a regular on/off switch, then possibly some residual energy is residing in the lamp circuitry and should eventually extinguish.

I expect yours is defective. Mine runs continuously on 14vdc from a little wall wart powersupply. A 12v lead battery fully charged will be at ~13.7 (14vdc). Note that your bulb is also designed to run on ~12VAC from a little transformer and no rectifier like a doorbell transformer. I suspect the bulb would have the same issue using AC power.

I'm sure it would get hot at the highest setting but why would you leave it on for this long at the high setting? If you have a need for a portable light that puts out this much light for an hour you should probably be looking at 12 volt light bulbs rather than a tactical flashlight.

I did not have success with them, only temporarily. Due to higher voltage, 4.2 Volts, they have a regulator that cuts off when ever he wants and your flashlight will go dark, even do the voltage will read 3.2 on the voltmeter.I used them in a NOVA flashlight. Rechargeable batteries made 2 or more years ago with different technology worked fine, and their initial voltage after charging was 3.2 V. Honestly I don't know what are this batteries for, I will not risk an electronic devise with them. I am an electronics engineer. Sorry Tenergy.

There is a small door on the side of the lid. Open it and you will find the UV switch. One of the respondents wrote that he experienced melting. A broken or loose bulb can create a short. Make certain that your wall outlet has a GFCI. This will cut the power in the event of a short, and keep you and your fish from being electrocuted. Water and electricity don't mix. Pick this up at a big box store for about $10, or call an electrician. But don't run your tank without one.

I inserted the bulb to the base, but it is very loose. Since I installed it between A-Coil and Blower, I worry that it can go off by itself and be blown to everywhere by the blower. Any solution?

I tried electrical tape (for some resistance to keep them from popping out) but it didn't work. Once they come apart, might as well consider it a handheld flashlight.

You gotta make sure that the batteries are completely charged that means the light turns green on the charger and then off to flashlight still don't work grab a voltmeter and check your batteries because they should be 3.7 volts each

That's the problem with this flashlight. They don't offer a replacement bulb. They should publicize this fact before anyone has to buy this item.
