Has anyone ever measured the warm versions? I see some people have “estimated” the OTF of some of the cool ones at 840 (The Wizard Pro 1.5), but has anyone tried measuring one with their integrating device? I’m currently working on my review for the Xtar WarBoy, and it literally blows everything else out of the water. This can’t be right, right? I know that my device tends to favor things that throw, but even my Spark ST6 seems low and it has a reflector.
Ok here’s what I got. These are all after 30 seconds, per FL1- mind you.
I’ve calibrated using 2 Fenix lights. The 8 lumen mode on my Fenix LD15… and then used my HL50 headlamp on the 55 lumen mode. So by both of the those metrics my figures above would drift by 10-20 lumens… this is using different cells too. Anyone here measure headlamps?
The wizard pro is rather floody with that diffuser, your measuring device could be a bit fooled by that, could be 10%. And warm leds are less efficient, that could account for the rest of the difference.
The warboy is supposed to put out 1000 lm so you're not far off that number, right?
Yeah the Warboy seems accurate. I put on the small optional reflector for the Spark SG6, and the ST6 has a reflector. The SG6 is rated at 840 by the manufacturer and ST6 is 460- both would be most similar in optic to the Warboy. Only the Xtar is close to it’s estimated target. I don’t see many people measure headlamps, so I was curious if anyone else has done testing of them. I figured my device would not favor the Armytek optics or the flood of the SG6 (which is why I put the reflector on it).
I just checked my Tiara A1 Pro with a Windyfire 14500 battery at 3.92v(I’m thinking it’s a NW version). In my light pipe, which is roughly calibrated to djozz’s integrating sphere it measured 535 lumens in turbo. I’ll update my numbers once the battery finishes charging.
Is this the newest version? Mine is the first generation “Warm.” Are you measuring initially or at 30 seconds in? This makes me feel a bit better… not the 890 claimed off a 14500. Which I knew wasn’t accurate anyway. I feel like the Tiara and the Wizard should both be within a hundred lumens of each other initially anyway because they’re both XML2 based and use a lithium ion battery. Plus I wasn’t measuring every single light at precisely 30 seconds… sometimes 30-40 seconds. The initial drop on these lights is pretty big so 10 seconds can make a decent amount of difference sometimes.
It’s possible… Although the Hl50 I used as a calibration device is a Neutral tint. I think I saw another review that mentioned the warboy was outputting over 1000 lumens too. Headlamps don’t seem to get the full review treatment as much- because it’d be nice if there was a bit more data. Also I have the predator pro warm… And that one seems to come close to what others got out of it.
Mine is an XM-L2, not a warm white as far as I can remember, but I don’t know what generation of the Tiara A1 Pro it is, or what the differences are between the generations.
With a charged up Windyfire 600mAh 14500 I measured 650 lumens. Pretty far off the claimed 950.
If you bought it less than a few months ago it’s probably the newer version. If you got it earlier this year or last year it’s probably the old version. I’ll do one more test off a brand new battery and call it a day. You probably have the cool white- it should say Warm White visibly on the exterior of the light if it is the warm white. It’s actually more Neutral than anything, but I won’t split hairs.
Thanks for your help, it was much appreciated.
Anyone else feel free to post headlamp figures if you have them.
i measured my Armytek Wizard Pro V2 Warm with Djozz´ IS. I was a bit surprised that we measured only ~750 Lumens on Turbo. But this seems to be normal because Armytek measures LED Lumens (1120) or OTF Lumens (975) instead of ANSI Lumens.
