Last Update 19-03-2021

Lumintop FW4A Flashlight Review, this Lumintop is part of the FW from the BLF members Series, it shares the specs of the FW3A, only, it has four! LEDs to gain some more lumens, a larger floody beam and some more distance.

It is available various led options but only grey in color

I chose the SST20 4000k NW FA3 95CRI as I’m in love with the creamy tint and very high CRI (Color Rendention Index), colors truly pop up and everything shines in a natural way

It runs on 18650 Li-Ion rechargeables, very easy to find and cheap to operate, I use Sanyo 18650GA’s they are 3.350mah and 10A, the quality is solid and they work well in any climate.

Lumintoplighting.com offers a Samsung 35E as an additional option, the Sanyo is for me better, not only being often cheaper but it seems holds some more mAh capacity and is 10A vs 8A, although I don’t visually see much difference in output.

The Threads are smooth as is the anodization, for the price it’s a wonderful light, just don’t exagerate with TURBO as it obviously gets VERY hot. If used at home/work it dissipates less than outside, driving the boat at night it was only very warm but not impossible to hold.

Mine has no problems with the inner sleeve or the switch.

The switch needed a few presses to operate correctly, it was probably in need of a break-in, now it’s flawless.

I got the light 3 months ago and it’s one of my favourite EDCs, I have got no box pictures, surely there are plenty around! as I am more user oriented and I’m not as tech-savvy as others, here are some detail and user-oriented pictures.
