I got the if24 when it got released and it's an awesome light i have a Molicel p28a and it makes a noticeable difference it has some power and with the Molicel it sustains the output for a good amount of time. I can't wait to get the pro model cause I love the sft-40 and tint plus the range. I live in the woods borh are great and have there uses plus I got the if24 for dirt cheap. I can't wait for Amazon to carry the pro cause I have some gift cards. Great light's tho honestly i never thought I would love these light's somuch I highly recommend them.

They're just so versatile given all the different LEDs, plus that spot beam. Surprisingly throwy. Not sure when it will come out on Amazon. Only seems to be selling on Sofirn's website at the moment, maybe Aliexpress.

I always though that any flashlight that has a good flood side cob should concentrated on range for the main beam. Some combination lights try to compromise and make a flood beam for the main emitter. The only way they get range is either specialize optics or high output. I like the pro version best because of the capabilities. I don’t own either version but i do have the Sofrin IF22A.

I like lights that optimise for either flood or throw in a specific beam. But you do get LEDs like the XHP70.3 Hi that produce a heap of light and throw at the same time.

@@DarrenYeoYT I find it confusing that both Sofirn and Wurrkos stamp the packing boxes with labels stating "XHP 70D-6500K" instead of "XHP 70.3-6500K". I delved into the rabbit hole and found a very complex world of LED order codes on the official Cree website! 😐 Apparently Cree divides the XHP 70.3 into two major branches: the 70.3HD and 70.3HI. The former is a domed emitter designed for High Density, while the latter is a flat (domeless) emitter designed for High Intensity. Originally I had thought "HI" meant a high Color Rendering Index value!

Nice..think i'm going for the Pro model

Yep that's my choice too.

Could you possibly do a run time comparison vs lumins of the two lights? I am suspecting the buck will be a fair bit more efficient and hold brighter. I have a wurkkos FC13 on order for cycling. But think I may send it back and get the pro one of these! I assume (hope my usual circular mount will grip it. May check with sim size block of wood)

I have individual review videos of each on my channel, the runtime graphs are included in both. But I didn't run any longer runtime tests until the light switches off. but for sure, the buck version should have sustained, flat output, whereas you will see the non buck version slowly drop in output over time.

Looking at the manuals on Sofirn website the Pro version has better battery life per output in the lower modes. example low mode is 10lm for 115 hours on the IF24 and the IF24Pro is 25lm for 75 hours. I tend to like the more efficient light and the one with the most throw so it will be the Pro for me 😀

where are the comments?😮

Yeah good question haha

I liked the comparison review and the night time demo on the fairway. IMO the IF24 doesn't have the reach unless its output is equivalent to the 4000 lumen IF23 or has the same emitter and reflector as the IF24 Pro. Therefore going the distance involves either increasing the lumen output or using a tightly focused reflector. 🙂 From my crude understanding, a boost driver increases the battery voltage to match the demands of the LED emitter. An FET driver is the cheapest of all and performs no voltage regulation. A buck driver works quite the opposite and it reduces the voltage to match the needs of the emitter. Any idea why Sofirn opted to add a buck driver instead of a boost driver for the IF24 Pro? I'm scratching my head over this one. 🔦🤔 Well, I'll probably get the IF24 Pro next year. I've already exhausted my budget for FLs for this year alone! 😱

A lithium ion battery delivers 4.2v. The SFT40 is a 3v emitter, so the battery voltage needs to be reduced, hence the use of a buck driver. Boost drivers are only used when the LED(s) need higher voltage than the battery can supply.
