Hello! I need some help deciding which LED to get in a Convoy M21B. I am trying to decide between the B35AM and the GT FC40. I know both LEDs are high CRI and both are more on the floody side, but could someone give me a quick run down of the pros and cons of them compared to each other? As far as brightness, efficiency, throw, tint, etc.
Also, I know that tint and color temp are just a matter of preference, but I would like to hear some peoples’ experiences with the different color temperatures, especially with these LEDs. I am thinking of getting the the B35AM in 2700K and the FC40 in 3000k, but most of my flashlights are around 5000k and the lowest I currently have is some SST-20s in 4000k, so I am not sure how I would like it. But, you never know until you try, right?
The gt-fc40 is a real crapshoot in terms of tint, whereas the b35am is much more reliable. I much prefer the b35am for this reason, the 4000k fc40 I bought is horribly green
Thanks guys! Sounds like B35 is the way to go. Also, I would probably prefer the 18650 version, but I want the to try the MAO coating. I couldn’t find the M1 with that.
I love over kill!! But really, unless one just cannot tolerate the minimally larger size of the light, the 21700 is just the better choice. For low draw the just the 5 Ah vs 3.5Ah capacity is well worth it. For me, I just don’t find the size difference to be significant.
I have a B35AM 4500K and a GT FC40 4000K.
I definitely like the tint of the B35AM better for sure.
The B35AM is in a M21A with a Green AR Coated Lens and the GT FC40 is in a S11 with a Magenta AR Coated Lens, so it’s not really an apples to apples comparison.
The first B35AM I had, had the most beautiful tint, I sold it to a buddy and built a 2nd one.
The first one definitely had better tint than the second one.
After replacing a Magenta AR Coated Lens with a Green AR Coated Lens, the tint was Much better.
So my suggestion is to ask for a Green AR Coated Lens in the Order Notes just to be safe!
I currently have a SFN55.2 in my M21B and I’m seriously considering swapping the Emitter and driver with my S11 just to try out the GT FC40 in a different host with a Green AR Coated Lens.
