Fenix HT30R vs TK30 - Battle of the LEP's  

So the reason that the cd rating can be twice as much, but the throw is so similar is that throw is a function of the sqare root of candela over 0.25 lux. In practice what this means is that you have to 4x the candela to 2x the range. So for example, a 25,000 cd light has a range of 316 meters. And a 100,000 cd light has a range of 632 meters (slightly rounded, but you get the point.) The actual equation is D=√(cd/0.25). So if you know the cd of a light, multiply it by 4 and take the square root of that and you have the ANSI rated range in meters.

Although similar in brightness, HT 30 the light beam is more pointed, acute and allows you to reach a greater distance.

I'm liking the TK30 bro!! Thanks a shit ton for the comparison👍

The TK30 fits the pocket or rifle/pistol mount. You can even buy a remote pressure switch. The HT30 is too large for either but is not much difference in power. I like the TK30 better.

I was leaning towards the tk for many of the reasons you highlighted. Now i have no doubts! Cheers from Wisconsin USA!

Because Candelaria is only a measurement of intensity of light. Intensity doesn't dictate distance.

thanks for the content )

300k vs 600k candela: Doubling the power doesn't necessarily allow for double throw distance just like 400hp vs 800hp doesn't allow your car to reach double the speed in the latter. You'll see more noticeable gaps at lower power but the higher you go, is like taking off a fraction of a second off your quarter mile. Aside from a different design in the lens and also the electronics of these two flashlights, there will always be atmospheric conditions that will affect the performance output. Welcome to Earth!

Does the memory work for strobe on the TK30? Or just the high and low constant beams?

Thanks for a great comparative review of these light-throwing beasts! One question, if you still have them - do you know if the front protection window is made of glass (or sapphire crystal etc) or from plastic/polymer?

I think these LEP lights would make great spotlights for nighttime boating. Great for looking for buoys and that sort of thing.

Dude THANK YOU! I’m a Fenix fan boi and want an LEP for my night hunting rifle. I need just enough flood to be useful at distance. Thank you for posting this comparison!

Does anyone know if it's possible to switch my tk30 tailcap out for a ht30r cap?

I'm with you....the TK30.

What is the best long range flashlight you recommend?

very good video and thanks for using metric system!

I like the HT30R both are good lights I don't know if liteshop is your sponsor but man that's a high price NealsGadgets and Flashlightbrand have way better deals.
