  • Dimensions: 3.9 x 3.9 x 3.9 inches
  • Product Weight: 3.53 ounces
  • Type of Battery: lithium-ion

The Streamlight 66134 is a pretty basic rechargeable flashlight that does not have many fancy features. However, it is still a very well-built model that is durable and long-lasting.

The head gasket is properly sealed to prevent water from entering the device. It is essentially IPX-4 rated, which means that this unit is water resistant. Additionally, it is also impact resistant for a distance of up to 1 meter. This makes it an excellent EDC flashlight if you want to use the Streamlight 66134 that way.

Further, the shell is made from an aluminum alloy that is also lightweight. There are grooves on the handle making it antiskid and generally comfortable to hold for an extended period.

It doesn't output a lot of light as 90 lumens is the maximum the LED driver can manage. But, this is still a good thing since it has excellent runtime autonomy and the battery can be fully charged in 2.5 hours which is fast.

Moreover, this model is delivered with a USB charging cable.

By far, one of the best features of the Gold Armour is its powerful brightness of 1600 lumens. Indeed, this is the brightest rechargeable flashlight in this entire review.

The Gold Armour is not a very compact model as it has a length of 7.9 inches which is very tall by flashlight standards. However, it gives the flashlight a good grip and will make an excellent tactical rechargeable flashlight.

Moreover, its massive weight of 16.8 ounces is on the heavy side but it reinforces the fact that this unit is better suited as a defense weapon as well as an illumination tool

One thing that we like about this unit is that the handle has antiskid grooves making it very ergonomic and comfortable to hold. It will also not slip when held with wet hands.

It comes with many accessories like a holster and a carry bag, as well as a charging kit.

If you don't require a very portable rechargeable flashlight but need one that is durable and can be used as a weapon, then this unit is the best rechargeable flashlight that money can buy.

To make it a better outdoor flashlight, it is waterproof and can be even be operated in the range if necessary. However, it cannot be used underwater under any circumstances.

But one of the best things that we like about this product is its zoom function. Indeed, the beam distance can be adjusted quickly and easily.

How to Buy the Best Rechargeable Flashlight

Photo: Fenix

When purchasing a rechargeable flashlight online, here are some very important things to take into consideration.

1. Lumens

The lumens of a rechargeable flashlight is basically an indication how powerful and bright the device is.

If you plan to use your flashlight for an extended period, for example, when doing a night shift then it is probably best not to go with the highest lumen.

A model that has the longest runtime in this situation will make more sense.

2. Beam D istance

The beam distance basically shows you how far the rechargeable flashlight can shine.

Essentially, a flashlight with a long beam distance shows that it has a more powerful and brighter LED driver inside.

However, all will depend on your usage and need. If you require a longer beam distance, then this is an important factor to consider.

If not, you can ignore the beam distance as most rechargeable flashlight may not be champions at shining the light at a distance but do very well at close range.

3. Budget

Always prepare a budget before you go out and buy a rechargeable flashlight. Whatever you do, stick with this budget and do not go over overboard.

It is very easy to spend an excessive amount on the rechargeable flashlight that has features that are totally unnecessary and that you will never use.

4. Recharge Time

Since by their very nature rechargeable flashlights are meant to be recharged, the recharge time is an important factor to account for.

The best LED rechargeable flashlight on the market generally does not take more than 4 hours to recharge fully.

If you want better recharge time, then it is probably wiser to sacrifice lumens and opt for a less bright model that offers a faster recharge time.

It is all about balance and it will depend on you need, first and foremost.

Rechargeable Flashlight FAQs

Question 1: Do You Have To Fully Charge Rechargeable Batteries Before Using Them?

Answer: Yes and No.

In general cases, you don't have to fully charge a rechargeable flashlight before using it.

They will start delivering good performance even if their charge level is significantly lower than full, and only affect the overall runtime of the flashlight.

However, since most rechargeable flashlights use lithium-ion based batteries, it is best to wait for the flashlight to totally discharge before fully charging it.

This method has been proven to work best with lithium-ion batteries as it helps to extend its lifespan.

Question 2: How Long Do Rechargeable Batteries Last?

Answer: There is no right or wrong answer for this.

It will basically last a long time if used moderately and recharged only when the battery dies.

However, it will mostly depend on the brightness of the LED driver, the mAh of the battery and how often it is recharged.

All those factors affect the lifespan of the rechargeable battery. If you want a long-lasting battery, the best advice is to choose a model that has a replaceable battery and buy a couple spares.

Question 3: Do You Need An Extra Product To Recharge?

Answer: Yes.

You will need a battery charger to recharge the batteries. Most of the time, this charger is provided with your rechargeable flashlight.

All you will have to do is to pop out the rechargeable battery and place it in the charger.

However, not all models allow this. Some rechargeable flashlights have an in-built lithium-ion battery that cannot be removed.

For this type of model, the manufacturer normally provides you with a USB cable that you connect to either a computer, a 5V power outlet or a power bank to recharge the flashlight.

Question: 4: Is There A Way To Prevent Shortened Battery Life?

Answer: Yes.

As with everything, the worse can be prevented. To promote the battery life of your flashlight, there are a couple of things you can do.

Responsible Use: Always ensure the flashlight is switched off when not in use. Some people will leave the flashlight on for an extended period, even when they are not actively using the unit.

Use Higher Capacity Batteries: Choose models that use higher capacity batteries like 18650 batteries rather than smaller AAA or AA batteries. 18650 batteries can hold a charge for longer and will also allow more recharge cycles before dying out.

Recharge Cycle: Only recharge the battery to full when it totally dies. Don't put it on the charger everytime you use the flashlight, especially if you use it for only a few minutes.

Lithium-ion batteries last longer and are more efficient when they are charged just after a discharge and not when the battery still has charge.

Question 5: How Do You Clean A Rechargeable Flashlight?

Answer: Most rechargeable flashlights can easily be opened for maintenance. First remove all the components, including the tail, head cap, and rechargeable battery.

Then dip an earbud in isopropyl alcohol and clean the inner part of the shell. The earbud is long and small providing you with easy access to the inside of the flashlight.

Note that you can use any cleaning liquid, but isopropyl alcohol will clean and disinfect at the same time. This alcohol is also quite safe for cleaning electronics.

Which Rechargeable Battery is the Best Option?

Photo: BYB

There are several types of batteries used in a rechargeable flashlight. The 3 most common types are:

  • Lithium-Ion
  • NiCd (Nickel Cadmium)
  • NiMH (Nickel Metal Hydride)

Of all the 3 types, lithium-ion is the latest generation battery that is more efficient and has a longer recharge cycle.

It is basically a replacement for NiCd batteries and most modern generation rechargeable flashlights are expected to have a lithium-ion battery in contrast to a NiCd one.

Even if NiCd batteries are much cheaper than lithium-ion it is always a good idea to choose the latter as it is simply more efficient.

Additionally, lithium-ion batteries have more recharge cycles which makes it longer lasting than NiCd batteries.

On the other hand, NiMH batteries are higher capacity batteries that have no memory effects. Moreover, this type of battery is very energy efficient as well as being environmentally friendly.

However, despite NiMH batteries being superior to NiCd, they are still inferior when compared to lithium-ion.

All in all, when choosing a type of battery for your rechargeable flashlight the most important factor remains the recharge cycle, the battery efficiency, and its durability.

So far, lithium-ion is the only proven and tested battery type that works well in a rechargeable flashlight in the short and long term. We recommend the lithium-ion battery above all else if you want peace of mind.


We come to an end of this review and guide. We hope that by now, you are in a better position to choose the best rechargeable flashlight for your need. As we’ve seen, most of these tools are heavy-duty and very easy to use.

The amount of light they can output as well as their ease of use is legendary. They can easily be used as an EDC flashlight if you so choose.

Even if you have never used a rechargeable flashlight before, you will simply fall in love with them the second you switch them on. But, in case you have still not found the best USB flashlight, we recommend you read our review and guide again.
