Excellent product.Review by Jenni
I work in ophthalmology and need a good sturdy torch to check the pupils of patients. Would highly recommend this product and buying it from Brightnite online, fast delivery and great to deal with. It is so good that everyone at work is now borrowing it. (Posted on 23/05/2017)
Quality Light at on a Budget Review by Peter
---- ----
Due to its relatively complex mode selection process, the Ti4 does pose some difficulty as an EDC flashlight. It may be challenging to select the correct lumen outage in a pinch, and if the the user is not familiar with the light than we can guarantee mode selection will present a problem. However once familiarised, the different modes can allow for correct lumen outage in every situation. Either reading late at night in a tent with the firefly mode or out on the water using the Ti4 as an improvised spot light (thanks to its 50m throw) and utilising the full 252 lumens.

During the carrying and testing of the Ti4 the WLC has come to some conclusions about the flashlight. From now on, the WLC will be using the Ti4 as a dedicated adventure flashlight. We will remove it from everyday carry and will aim to replace it with a single mode flash light due to the comments previously mentioned. We also believe that it is more suited to the role of a dedicated adventure light as it gives more options to the user in different situations.

This penlight is fantastic for my pre flight inspections of the aircraft I fly. Bright enough to inspect the areas I need prior to flight and then it fits right back into my pen pocket, great stuff (Posted on 7/03/2017)
