Question: What kind of batteries does it take?
Document: When buying batteries for these super lights, make sure that you buy protected batteries as the batteries that are not protected don't always power these Searchlights making you think that the lights are defective when in fact they are not.
When it arrived, I was surprised to see it took batteries I had never seen. It does NOT come with any. So I went to the battery specialty store and bought four batteries and a charger for $$48.00.
The flashlight works really well and has a lot light output and is very durable with fantastic runtime on my cheap batteries (more than 3 hours on high, all night on low)...The downside: It is approximately 1000 lumens, at least mine was, and this is obviously a lot lower than the advertised output, and there is essentially no heat sinking for the LED's as the LED plate is seperated from the body of the flashlight by silicon glue.
The 4 LED NitecoreTM 26 is at least 3 times brighter (5X costlier too) in it's turbo mode and the 3 LED Klarus RS80 is at least twice as bright. Worth $228 list price? No way! At $65.00 it's a questionable purchase. Several smaller flashlights can be found that are brighter and cheaper. They just won't have the run time this light has b/c of the batteries.
This Searchlight runs on four 18650 batteries connected to the Cree LEDs in parallel which means the LEDs get only 3.7 volts, but the batteries last a lot longer than if they were connected in series. The Searchlight worked well for the first few times and then quite. My options were to send it back to Amazon or fix it. I paid far below the original MSRP so fixing it would be my best bet.
The unit came with one led dead out of the box. Clearly QC is not a priority with this knockoff. Still a bright flashlight (but no where near 6000 lm as advertised w/the 5 remaining LEDs) and MUST use protected batteries as they are connected in parallel-NOT series. Poor finishing on the body of the flashlight but physically sturdy. You have to be careful not to grab too hard or bang yourself against the sharp edges of the milled front and sides.
this devic was delivered in less than a day. not much in instructions but it is fairly simple to figure out. have not tested water proof status yet. but otherwise is was a great investment
i ordered 6000 lumens searchlight not 3800 lumens look at my order and get back to me, maybe get me the right light.
We purchased this for my husbands work. He works nights in the oil fields and needed a very bright light for dark locations. This supplies all the light he needs to be able to do his job safely.
This is, by far, the brightest small flashlight that I have ever seen. I bought it for my emergency kit, and it easily replaced my 4D Maglite that was previously in there. I LOVE it cause it's so compact.
Answer: yes
