Olight Arkfeld Pro vs Olight Baton 3

“I've been testing [FFL5009R](https://www.firefly-outdoor.com/en-ca/products/ffl5009r-cri98-5050-emitter) from Firefylite and [NTG50](https://intl-outdoor.com/noctigon-ntg50-6v-led.html) from Hank, both of which are the same LED as the [Hopthink FL5009R](https://budgetlightforum.com/t/led-test-review-hopthink-fl5009r-custom-5000-k-90-cri-this-is-something-new/227625) originally customized by a Chinese flashlight enthusiast. This is a quad die LED similar to XHP50.3 HI, but unfortunately the wide die spacing makes it difficult or impossible to use in many lights due to extremely bad donut hole beam artifacts. Diffusion film or an optic that diffuses the beam clears this up nicely, so the Zebralight H600F (with frosted glass) makes a great host for these new LEDs. Here's an example of a donut hole in an Olight Baton 4. Most lights I tested had this issue, even with OP reflectors. https://i.imgur.com/Ytg9NBM.jpeg https://i.imgur.com/bO5ZpDB.jpeg In the H600F, the beam is a little more throwy than stock, and the frosted glass does an excellent job of smoothing it out. NTG50 is extremely rosy (other than the 1800K not included in this post). FFL5009R was an expensive disappointment for the most part. I ordered 35 samples and tested them all individually, and only 4 have nice enough tint for me to use for modding. My preference at 5000K is always neutral tint, and the hand picked sample I used here is very nice. The stock H600Fc is my own personal hand picked light, and has nicer tint than average. I was happy to see the output is nearly as high as the stock light for almost all CCTs. The H600 is still a really great compact 18650 headlamp, and these LEDs give it a nice update for emitter swaps. NTG50 will definitely satisfy the rosy tint aficionados. FFL5009R is a little hard to use for modding if I only get 10% yield, but the sample I used here is a beautiful pure white. Most of the lights in this NED are already purchased, but the 5000K FFL5009R is still available. Unfortunately I only have a single extra H600 in stock right now, but I'm hoping to receive more in time that I may be able to ship some before the end of the de minimis exemption on May 2. #Output Level | 2700K NTG50 | 4200K NTG50 | 5000K NTG50 | 5000K FFL5009R | 4000K stock ---|---|---|---|---|--- H1 | 1223 (1181) | 1404 (1360) | 1418 (1386) | 1462 (1426) | 1548 (1476) M1 | 100 | 114 | 112 | 117 | 117 #Colour **H1** Sample | CCT | Duv | CRI (Ra) | CRI (R9) | Rf | Rg ---|---|---|---|---|---|--- 2700K NTG50 | 2773K | -0.0067 | 95 | 98 | 95 | 104 4200K NTG50 | 4531K | -0.0083 | 96 | 85 | 93 | 103 5000K NTG50 | 4908K | -0.0072 | 96 | 90 | 93 | 104 5000K FFL5009R | 5220K | 0.0020 | 96 | 83 | 94 | 101 4000K stock | 4273K | 0.0004 | 91 | 60 | 90 | 100 **M1** Sample | CCT | Duv | CRI (Ra) | CRI (R9) | Rf | Rg ---|---|---|---|---|---|--- 2700K NTG50 | 2666K | -0.0079 | 92 | 88 | 93 | 105 4200K NTG50 | 4361K | -0.0096 | 92 | 67 | 91 | 103 5000K NTG50 | 4705K | -0.0080 | 94 | 73 | 92”

“Looks pretty cool, but it's going to be a tough sell for people who already have the original Arkfeld Pro. I'd love to see a version where they have an option for a deep red SST20 instead of the UV emitter, then I would probably make the switch.”
