Lumintop SD75 Flashlight Review – A Car Headlight In Your Hand!

We’ve been doing a lot of night photography lately, catching the Milky Way at Waterton Lakes National Park in the Canadian Rockies and hiking in the dark out onto a rocky point to catch sunrise at Deadhorse Point State Park in Utah. We even hiked the Fairyland Trail in Bryce Canyon National Park after midnight.

We’ve also played with creating ghostly images by doing Light Painting in old buildings in Ouray Colorado.

A key piece of gear we have relied on for all of this is a Lumintop SD75 4,000 Lumen flashlight.

In the past we used Maglites and smaller LED flashlights to find our way in the dark and to cast light on the surroundings during a long exposure of the night sky. However, even the best of these flashlights was hopelessly dim.

Mark is a huge flashlight junkie, and he searched for a long time for a big and powerful flashlight to use for our nighttime photography excursions and to use when we roam around our boondocking spots at night.

He decided on the Lumintop SD75 flashlight.

This is a “search” flashlight similar to the ones used by law enforcement.

There are three power levels, and at max power it is a whopping 4,000 lumens.

The light it throws at max power is astonishing — it goes 0.4 miles!!

Walking in the dark with this flashlight is like holding a car’s headlight in your hand!

There is a strobe mode as well, and at max power strobe, it can run for 50 hours!

The Lumintop SD75 is made of heavy duty aerospace aluminum and has a hard-anodized anti-scratching HAIII military grade finish. The LED bulbs are the latest CREE XHP70 LED technology.

This is a serious piece of gear that comes in an equally serious suitcase!

The flashlight has its own suitcase. Don’t worry, it’s about the size of a very very big lunch box.

This aluminum suitcase has foam cutouts inside for all the goodies that come with it.

The flashlight comes with four lithium-ion batteries that are rechargeable. It also comes with a wall charger as well as a 12 volt car charger.

The flashlight packs into the suitcase in two halves. The battery pack is shown in the middle.

So, we can charge the flashlight batteries either in our RV or in our truck, whichever is more convenient.

There is a battery charge indicator light on the back end of the battery, so we know exactly how well charged the batteries are.

There are also two USB connectors for charging cell phones or other devices FROM the flashlight battery! That’s how much charge these batteries can hold!

Cap off: Battery indicator light, 2 USB ports + slots for a strap.

There are also two slots on the cap that covers the back end of the flashlight that can be used to attach a carry strap or piece of line.

One very handy feature for when we are setting up our tripods and camera gear in the dark is an LED taillight that attaches to the back end.

Standing the flashlight on end, this taillight illuminates the area all around the flashlight. This would be ideal in a tent or doing emergency truck or RV repair work in the dark too!

There is a quarter inch tripod socket on the side of the flashlight so it can be mounted on a camera tripod as well.

One feature we haven’t taken advantage of — because we haven’t been caught out in the rain or gone swimming with this flashlight just yet — is that it is water resistant to 2 meters!! It comes with extra O-rings to help keep it watertight as well.

I wish we had had this flashlight when we cruised Mexico with our sailboat. We had a 12 volt “4 million candlepower” spot light that we kept on deck during every overnight passage just in case one of us slipped overboard.

Of course, we wore harnesses and clipped ourselves to the boat at sunset and stayed clipped in until sunrise as long as we were outside the cabin. But there was always the chance that the quick release mechanism on the harness might accidentally undo itself or some other catastrophe might happen that would send one of us into the drink.

Frankly, there is no way in any conditions but the calmest seas that our spot light would have been bright enough to illuminate a bobbing head in the water.

This flashlight is so much more powerful, we both would have felt a lot more comfortable it we’d had it aboard with us!

If you are looking for a high quality flashlight for walking around your RV campsite at night, or for hiking in the dark, or for light painting old ghostly buildings in the wee hours of the morning, the Lumintop SD75 is a terrific choice.

It’s also a neat gift idea for that sweet hubby who loves gadgets and is so hard to buy for!!
