UF-1504, 1503, 1505 - multiple LED's tested for throw (just what you have been waiting for!!!)

It’s possible, but the light is about 8” above the table. Over 6 feet, it seems it would be minimal. I’m gonna try something new. I’m going to place the meter on the floor and hang the light 6’ high. It’ll be easier to adjust the meter.

I got 370 (380 at startup) at 3,8A. But my 1504 lenses are not clearest one(lot of color aberration)...

As I mentioned many times before we have emitter bin lottery (up to 15%difference) and lenses lottery(up to 20% difference among same batch of lenses)

So if got lucky 450 kcd can be done or even more...

And of course this is crazy work from N10sivern. I am very grateful for this...

Oh yes, he’s put a lot of time into the GB and testing too. I am grateful for all his efforts.

It is a emitter lottery, lens lottery and luxmeter lottery. I'm surprised that the numbers from different people are generally so close to each other :-)

Check the OP. I just updated with new data.

The 1503 was about 40% of the throw of the 1504 on both the XM-L2 and XP-G2. One was like 39.5% and the other 40.5%. Regardless, I think this consistency confirms my 1504 readings a little. As for the 1505, it didn’t like the XP-G2. I check my measurements two different times and got the same 34100 lux. Due to this, the XM-L2 U4 wins with the 1505.

Curious if you have any idea why the amps jumped so much with the second test of the XP-G2 S4 in a 1504? Or was it just an error typing it up?

Henry, read my note. I had to use a different DMM because I didn’t have any more fuses. It read higher amps on everything

D’oh, how’d I miss that! slaps forehead

Haha.

Any idea why the XP-g2 performed poorly in the 1505?

Thanks for more numbers. The XP-G2 S4 in the 1503 disappoints. In my shortened 1406, a dedomed XP-G2 R5 with a direct driver gives 230 kcd.

In general your numbers are not very far from what I measure in similar mods, perhaps yours are 5% higher.

No idea, in a T20 the XP-G2 is about 30% higher candela output than an XM-L2 from the dozen I’ve put together. Were they tested in the same host? Your XP-G2 numbers are spot on with what I get with an S2 2B in a T20, so either that’s low on your light considering the S4 2B shows higher output than an S2 2B, or your XM-L2 measured high.

Edit: your XM-L2 number is about 60% higher than I’ve ever measured a direct drive XM-L2 in a T20. I’m betting something is going on with that number.

I wonder……I didn’t use any retainer on the 1505 as I didn’t feel like soldering to the pill when changing out emitters. I wonder if the XP-G2 separated from the pill slightly and the LED was getting heat soaked. Hmmmmm

KKW, 458kcd. Tag, your it! :wink:

Next week I plan to work on my ghettofied wavien collar. Maybe I can hit 500kcd! :open_mouth: only 12500 more lux at 6’ and I’m there.

I challenge you to a duel!

Throws gauntlet down.

:bigsmile:

BTW, the advantage of the S4 2B disappears once my order from international outdoor shows up. :wink:

I’m currently assembling one with one of the S3 3A’s I bought from you, so the ball may be back in your court before the S4 2B’s show up.

Ha, no duel. I’m sure you will beat me to 500. I just wanna get to 500 just to say I could and did.

Oh, by the way, did you see the amps for the XP-L V6’s? I think it was you having issues getting the current out of them. I know there is speculation they are really V5’s from LEDDNA, but 1 bin should not cause that huge of a difference should it?

Yeah and the 3A should be to warm to dedome. Should be a nice tint though.

I’ve never been scared of a warm tint.

C’mon, this could be fun, let’s push the envelope on these things. Let’s take them as far as we can get them and then swap our final resulting lights. My goal is to beat my K50vn at 575kcd. I’m thinking I can definitely do it with a 1405, but the 1504 should be a nice challenge.

You got some terrible results for 50mm aspheric. In fact they are more than terrible if you ask me.

So maybe this time in this particular 1503 unit lens sucks?

Good 50 mm aspheric should throw 260kcd with 3,5A driver.

Well the S3 3A light I built only measures out at 343kcd without a collar, not going to be getting ahead of your numbers with that.

It staggers me that you are getting numbers 25% higher than I am. I really hope the S4 2B’s don’t disappoint when they get here.
