TerraLUX Pro-4

Convertible LED Flashlight

Lightstar Corp. has stepped outside of the box and created a TerraLUX flashlight that is perfect for any worker on the job. The Pro-4 is a high-quality, AA powered flashlight that features a magnetic 15" flexible neck, which means you can position this light around your neck or around an object if you are looking to work hands free. The flexible neck can be unscrewed and removed so the Pro4 can be used as a normal flashlight. The ability to go from a standard light to the convertible flexible light gives the Pro-4 superior versatility. As always, TerraLUX utilized the finest craftsmanship and durable materials that make their lights some of the most reliable in the world. This model features a high-visibility green finish. The Pro4 is also available in Titanium Grey.

Lighting Technology


The Pro-4 comes equipped with a CREE XP-G2 LED and produces a very bright 350 lumens in High mode. You can cycle through the five output modes via the tail switch and make your way down to the 25 lumen Low mode. The recessed tail switch prevents you from accidentally turning on the light while traveling or storing and also features momentary-on for that quick burst of light. All of this light is projected out from a polycarbonate lens with a precision-built reflector.


Widely Available AA Batteries

The Pro-4 gets its juice from two AA batteries, meaning you can find affordable power just about anywhere. The Pro-4's weather resistant construction means you can take it out in harsh conditions and still rely on it to work when you need it. Machined from type II hard anodized aluminum, this light is impact resistant up to one meter.

TerraLUX Pro-4 Convertible LED Flashlight - 350 Lumens Flexibility
March 8, 2015
Really flexible illumination tool. Use it as a straight Every Day Carry or by adding in the Flexible Extension and Magnetic Base you get a great work light that will stay where you put it, without a third hand.
  • Good range of lighting levels
  • Use as EDC
  • Use as work light in cramped quarters for plumbing, electrical and other household problems
  • Use as close-in work light in cars, trucks, etc.
  • None

A little disappointing
September 24, 2014
I have bought numerous TerraLUX products over the years and have been quite happy with them. I bought this to replace an old B&D SnakeLight. As a flashlight, brightness/control/body, it is excellent, and would have gotten a 5 star review.

My main usage is wrapped around my neck allowing hands-free lighting. The flex neck tends to creep, meaning the flashlight slips and has to be repeatedly adjusted. The magnetic clip has sharp plastic edges, so it tends to get removed and lost between those times when it would be useful.

I think this is a first generation TeraLUX product, so perhaps they just need to hone their mechanical design. Ordered a head mounted flashlight to replace this one.
  • Solid body
  • Good switch/control
  • Bright LED
  • Good battery life
  • Flexible neck doesn't hold position well
  • Magnetic clip sharp, not very strong, tends to slip from body

Great tradesmen light!
September 6, 2014
This is a great work light, good color and bight. I wish the switch was a little better and the magnet was a little stronger. The flex head on my light makes very little noise when you bend it. In short it is a very nice light.
  • Design, brightness, ease of use.
  • Switch and magnet strength (wish it was a little stronger, but still works great)

Very Good Light
August 29, 2014
This light has a magnetic base and a clip. It works great in places where a light might otherwise be not possible. The light levels are and offer a good variety of uses.
  • Wide flexibility
  • The switch could be better

Quite Innovative
July 29, 2014
I bought this light on a whim. I had never seen anything like it before and wanted to test it out for myself. To my surprise, it was very useful. The flex-neck stays in whatever position I put it and the magnet greatly adds to its versatility. I actually found it handy to wrap it around my neck when I was jump-starting my friend's car last week.
  • Convenient, versatile, unique, bright
  • Didn't expect the flex-neck to make a sound when I moved it, but it is not very loud

I realize that it already comes with a flashlight body, but can I attach the flexible head to my TerraLUX TruColor 220 body ? Does the Pro-4 memorize the last brightness setting used ?

Yes, the PRO-4 has a memory function. No, the PRO-4 head will not fit on any other flashlight.
