NiteCore LED handheld flashlight, suitable for activities such as camping, hiking, cycling, hunting, fishing, or during household repairs. It operates with a 18650 battery (not included). Additionally, it is hybrid and can also operate with different types of batteries. It has a powerful illumination intensity of up to 830lm. It is water-resistant, as it has IP67 waterproof certification. It weighs 250g and has a length of 15.2cm.
High Durability
The integrated ATR technology adjusts the brightness intensity of the EF1 flashlight according to temperature, operating conditions, and surrounding environment to maintain optimal performance. It is waterproof according to the IP67 standard and resistant to falls from a height of up to 1 meter. Additionally, it incorporates a 10mm optical lens made of epoxy resin with explosion suppression properties and is an electrical device of type II with an anti-explosive rating, although not suitable for mines.
Durable Construction
It is made of high-quality aerospace-grade aluminum alloy and features a military-grade HAIII hard-anodized finish. The lens has a scratch-resistant coating on both sides, making it highly resistant to drops of up to 1 meter in height. Additionally, it has a stainless steel clip with a Titanium coating for secure attachment.

Purchased a few days ago from a store in Thessaloniki. I haven't used it yet, but at first glance, I have the following to say:
- As a construction, it seems to be very sturdy, with the body made of thick aerospace-grade aluminum, the switch has no "play" and "locks" in each position, the glass in front of the lens is of considerable thickness. The threading of the battery compartment cap is fine, giving me the impression that it requires care during screwing to avoid cross-threading. Of course, it has lubricant on the threads and mentions in the instructions that it should be lubricated periodically, which I recommend because, as I mentioned, the aluminum material is soft and can damage the threading in case of cross-threading.
- As for brightness levels, I believe they are correct, with the 1st level shining a little (4 lumens) and lasting 150 hours, the 2nd level has strong lighting (320 lumens) and lasts 3 hours, and the 3rd level has very strong lighting (830 lumens) lasting 1 hour and 45 minutes. The times are based on a 18650 2600mAh battery; I set it up with a 3600mAh battery, which means that the operating times will be significantly longer. In all levels, the light beam is said to have a range of 270 meters.
- In conclusion, this is a well-constructed flashlight, sturdy, and this comes with a weight of 250 grams without the battery and a relatively small size for an explosion-proof flashlight. I will test it in the engine room of the ship (oil tanker), where the lighting is strong, to see if its beam stands out and if it has a satisfactory range, which is vital since certified explosion-proof flashlights usually do not have satisfactory performance. Regarding its resistance to water and dust, even from a drop from a reasonable height of the palm, I have no doubt that it will withstand. I will return with conclusions after boarding. I should note that it is reasonable for the brightness of the flashlight to decrease when the battery capacity drops, although there are batteries that maintain their performance almost until they are completely drained (high drain batteries).
Purchase outside skroutz
After 3 years of use, a problem occurred with the switch or some internal contact and the flashlight suddenly started flashing until today, 01/05/2023, when it stopped turning on.
Sturdy construction but not so resistant to impacts, as this caused the beginning of the end.
I will buy it again because
a. it has a relatively small volume for an explosion-proof flashlight
b. it has good response (always as an explosion-proof flashlight) in fuel tanks / crude, as I had no problem with the lighting and duration using a nitecore battery.
c. waterproof without problems after 3 years.
Its issues are
a. not so resistant to impacts inside tanks
b. minimal difference between the 2nd and 3rd mode
c. I believe the 2nd mode should have 830 lumens and the 3rd mode 1200 lumens, so it would be exactly what is needed for an all-purpose flashlight.
d. it should be able to adjust the focus of the lens (wide to narrow) to provide convenience in dark areas.
Instructions for sailors: after purchase, it would be good to invest in something to protect it from accidental falls and unnecessary impacts
I will come back after extensive use. For now, it appears to be quite high-quality and powerful. It has 3 modes, but the 2nd and 3rd modes are almost the same.
Well, as I mentioned before, I am coming back after 6 months of daily use.
The pros:
Mode 3 is very powerful.
The battery I purchased from the same company seems to hold up well and work well with the flashlight.
The cons:
Mode 1 is useless. The only use I can imagine is if you are trapped after an earthquake and need a faint light. It illuminates as much as a candle.
Mode 2 is too powerful and is almost as powerful as mode 3 when the battery is slightly drained. So there is no proper gradient between the 3 modes. In one mode, you have nothing, in mode 2 you're okay, and in mode 3 you're good, but only when the battery is fully charged.
The weight is a bit annoying.
The strap broke quite early, so due to the above reasons, we go from 5 stars to 3.
And as I mentioned, I am coming back after extensive professional use of 4 years. The flashlight is as good as new. It doesn't understand anything. It has been dropped in buckets of water and/or other liquids (like oil, petroleum), it has been hit, it has fallen from a height of one meter multiple times, it has fallen from a ladder, step by step. It hasn't suffered any damage. I wouldn't buy it again for the reasons I mentioned above. It is mainly useful in mode 2. Mode 3 becomes the same as mode 2 as soon as the battery drains a bit, and mode 1 is non-existent. Personally, I was bothered by its bulkiness and weight.
So yes, it is very durable and has all the certifications for explosion-proof, but on the other hand, it has several negatives that would make me look for something else.
