1. ## Consolidated Short Arc & HID spotlight Lux readings

There are lots of beam shots but very little measured lux@ 1 meter (CP) data on high out-put spot lights, This thread is dedicated to real world lux reading data of HID & Short Arc spot lights.
Ma_sha1 Lux readings are measured at 10 meter distance unless stated otherwise.
Equation to convert CP from lux reading @ X meters: CP= lux@ X meter times square of X
Example: Lux meter reads 10,000lux @ 10 meter distance, CP=10,000x10x10= 1 Million CP
Generally speaking, measure at 0.1X meters if its XK lux. If light is 10K lux or less, measure at 1 meter.
If light ~50K lux or less, measure at 5 meters. 100K lux, measure at 10 meters, > 1 million Lux, measure at 50-100 meters or more. >10 Million lux, measure at 100 meters or further.

Subscribed! This is a great idea. You should do this with LED lights as well. Nice having all the info in one spot.

3. ## Re: Consolidated Short Arc & HID spotlight Lux readings

Thanks! I have some led lux scattered around in my threads & there are a lot more led lux scattered around CPF, but my main interests have left LED. May be you should start a LED lux collection?

I started collecting the HID lux because I can hardly find any real numbers when I started moving toward bigger spot light mods. There are boat loads of beam shots & full of confusions & mis conceptions, took me a while to sort things out for my own understanding. Much more messy compared to the LED area.

No body believed me when I first reported Gen II Maxa Beam numbers, yet no one ever measured & published any numbers. I just got my 2nd gen II Maxa Beam, measured again, yep, in line with my first one.

4. ## Re: Consolidated Short Arc & HID spotlight Lux readings

Both lights are Gen II, factory rated 6 Million CP models.
Both Maxa Beam measured a little over 2 Million cps in my Extech EA30 lux meter. (#2 still need longer distance lux, I only have the 10 meter lux for now)

5. ## Re: Consolidated Short Arc & HID spotlight Lux readings

I'm not sure how I missed this before but this is a great data base! Couldn't help but notice that the figures seem a bit low compared to Ra's, mtbkndad's and Peakbeams own specifications of cp similar lights. You and Peakbeam for example both measure at about the same distance which makes me wonder about the 1/8 discrepancy ratio. Any thoughts?

I like sabbluster's idea of including LED's as well, although that would be an incredible amount of work. I measured the SR90 at 115,000 at 10M using your own adjustment method for the DX meter.

6. ## Re: Consolidated Short Arc & HID spotlight Lux readings

Excellent work ma_sha1 - a very interesting and useful resource!

I've added it to the Spotlights & HID - Threads of Interest sticky.

Thanks, I don't really know. One way to find that out is to reciprocally read each other's lights, they read mine & I read theirs, with such expensive lights, I doubt this is going to happen.

Another way is to see more CPFer go out & measure their MB with a lux meter, with enough data, the truth will come out even w/o direct reciprocal measurements.

Can you imagine my Moon Blaster been read by Peak's Beam's lux meter? with the 8x Conversion ratio, my 16 Million cp 120W P-VIP/ 9" reflector Moon Blaster will tun into 128 Million cps, over taking Ra's Maxa blaster for the #1 spot

I am about to install a G3 lamp, will publish an improvement data soon.

Nice result and your highest MB reading yet! That's a nice gain from the G3 lamp. Thanks for the update!

G3 lamp not installed yet. This is the BEFORE data, on g2 stock lamp, lux @ 61 meters., Previously I had the #2 light read only at 10 meters.

Max Beam #1, G2 Stock. 10 meter lux 1.7 Million ----- 100 meter lux 2.3 Million
Maxa Beam #2, G2 Stock. 10 meter lux 2.1 Million ---- 61 meter lux 3.2 Million

Gen 3 lamp upgrade on Maxa Beam #2 coming soon...

11. ## Re: Consolidated Short Arc & HID spotlight Lux readings

Gen III lamp on Top, Gen II lamp at bottom:

The Gen III lamp has been installed, but it won't focus to the spot, turns out that the Gen III lamp needs to be push forward more than the Gen II lamp to get to the optimized spot focus.

This can be achieved by pulling the lamp out a bit but the front spring is pushing it back after
the front glass window being installed. In order for it to stay, I ended up cutting about 5mm of spring out to reduce the pressure. Finally, I was able to get a nice spot & it looks a lot brighter than before.

Just when I popped a bottle of beer ready to chill out & do some lux measurements, see how much improvements I got, the up/dowm center mechanism crapped out, I lost the spot completely.

To repair that up/down mechanism, I had to take the head out, turns out the centering screw stripped its socket. I found a nut that works & JB welded above the stripped hole.
Got to wait for it to cure overnight now.

12. ## Re: Consolidated Short Arc & HID spotlight Lux readings

New update:

Maxa Beam Gen II, #2 with Gen III lamp: 75W Xenon short Arc, 5" Hi End Reflector 6.1 million Cps (Measured at 61 meter distance)
4.6 Million CP when measured @ 10 meter

it doubled the lux of before on stock Gen II lamp,
The optimized focus made spot much smaller as well. My "simply pulling the lamp out" method on the post above didn't work, the lamp slided back when I was done. In the end, I installed a 3-4mm "spacer" to the bottom side of the Gen II lamp,
that way it can't slide back & I was able to achieve ideal focus.

ma_sha, Have you completely forgotten my remarks about 'optical arc displacement', months and months ago...??????????
And, it was not the optimized focus that made the spot smaller, but the abcence of 'OAD' !!

Never mind... You solved the problem.

Regards,

Ra.

15. ## Re: Consolidated Short Arc & HID spotlight Lux readings

Ra,

You are absolutely correct, I forgot to mention the new lamp solved the optical arc displacement issues from the old straight tube lamp. My apologies

I wonder if the lack of OCD might in turn helped made the smaller focused spot possible?
neither one of my stock maxa beam can focus the spot this small.

Apologies accepted!

Remember that the arc-area resonsible for throw, happens to be extremely small (a few 1/100 of a mm!)
Small enough to show different results, even within the narrow tolerances of the electroformed reflectors and round shaped bulbs!
So you cannot compare different Maxabeams on focused spot geometry, they all will be different!
The more perfect the reflector, combined with the total abcence of OAD, the smaller your spot will be (at infinnity..)

Regards,

Ra.

17. ## Re: Consolidated Short Arc & HID spotlight Lux readings

Ma_sha, would you want to add the CSWL night reaper? IIRC what i saw is a 3" reflector. Measurement is about 2 mins mark. 900k, DX meter. 250 lux max at 60 metres. Unfortunately the PH50 is not in the country so i could not measure that.

I have the 60m spot marked out, i can go there again to do my other lights.

18. ## Re: Consolidated Short Arc & HID spotlight Lux readings

Sure, I added it to the list. Can you measure it again when you do the other HIDs? See how it go up against your Sanmak SM5200, 100W Mod, may be use the Sanmark to calibrated it?
The 900Klux seems to be High for the 3" reflector/50W, long arc HID. It's even higher than the 75W/4.25" reflector Barn Burner,
also more than 2x the lux than Polarion X1 (40W), which already is a super performer with Polarion 3" High quality reflector, maybe you got a super duper performer? 10W more power would not make than much gain.

19. ## Re: Consolidated Short Arc & HID spotlight Lux readings

I assume white copy paper was your target surface?

20. ## Re: Consolidated Short Arc & HID spotlight Lux readings

Just added 3 more HID flashlight lux, those were measured by shinetop, the man behind the Fire-Fox 1, the world's smallest 35W HID.

--MicroFire Warrior III 3" SMO reflector, 108,000 cp (measured by shinetop, 3 meters)
--6600mAH ebay HID 35W, 3" SMO reflector, 103,500 cp (measured by shinetop, 3 meters)
--Fire-Foxes 1(火狐2009), 2.6" SMO, Peeled naked bulb, 148,500 cp (measured by shinetop, 3 meters)

21. ## Re: Consolidated Short Arc & HID spotlight Lux readings

Sure....i thought it is high too. That's what triode888 and I got (it is triode888's). I can double check against my M3X Olight/TK70/Aliexpress 65W. It is 250 @ 60m, can't be a wrong reading as the DX meter goes 200 (it would not give a reading here, so it could not have been 25.0), 2000 and 20000. Can't be low batt as i just changed energizer cells. I'll verify again. I'll see if there are any reflective surfaces, but unlikely (that'd also show up with my HIDs when i verify again)

We measured the Surefire UBT3 TIRed XM-L. It calculates out to be 61k, 17.0 at 60m.

22. ## Re: Consolidated Short Arc & HID spotlight Lux readings

Good news, found the error. It is not 60m, but 45m. My tape measure is 7.50m, so i guess got messed up there and measured twice more (lost count or something). 45m is correct, i verified twice.

250 x 45^2 = 506k for the CSWL night reaper. Measured at 2 min mark approx (triode888 mentioned it drops to 40W after 10 mins)

Surefire UB3T is 17 x 45^2 = 34425. DX meter pls.

23. ## Re: Consolidated Short Arc & HID spotlight Lux readings

Correction Applied!

Thanks so much 2100, 500K is still extremely impressive, about the same throw as the Franken Mag shot arc I made, which is also 50W but runs on UHP short arc lamp. The number make perfect sense vs. the 400K lux Polarion X1.

UB3T using TIR is also very impressive, just shy of 2.8A/rebel SMO XML throw, but many love the TIR beam.

24. ## Re: Consolidated Short Arc & HID spotlight Lux readings

No problem. BTW if anyone is wondering how did the UB3T land here, the guy got a sister in US and she bought + brought it here.

All sound perfect except the timing, right when the M6LT getting released

26. ## Re: Consolidated Short Arc & HID spotlight Lux readings

Just got back from testing my Maxabeam (gen2 with parkerVH adapters and Ushio UXL-75XE bulb)
I'm using a photographic light meter, which reads in EV at 100 iso and can be easily converted to lux using charts found on the Internet
- the numbers I got were 6EV (160 lux) at 150m For 3.6 million cp on low
And 7 EV (320 lux) at 150m for 7.2 million CP on high

(carefully focused for the brightest beam, then aimed at my wife, who read the meter)

There may be errors though, although I did try 3 times for each setting, and averaged the numbers

27. ## Re: Consolidated Short Arc & HID spotlight Lux readings

Added to the list. Your numbers are pretty close to mine with UXL-75PB lamp measured at 61 meter.
I think you did it right although the method is unusual.

the method is unusual only because of the tools i have, if i had a normal Luxmeter i would have tested it ages ago.
Glad i did it right and its pretty close to what others have measured.
the bulb was freshly adjusted at a reasonable distance the night before too, a little knock and the CP will drop dramatically as the Arc is no longer at the correct focal point

and i think you made a mistake in the listing
Maxa Beam Gen II, #3 with UXL-75XE lamp: 75W Xenon short Arc, UXL-75PB lamp -7.1 Million cp
(Measured by echo63 @ 160 meter distance)

specifically the
UXL-75PB lamp -7.1 Million cp its a UXL-75XE lamp
