Preliminary XP-G 2 real word results

 

Folks,

  Just got a knock on the door and it was the mailman with a big yellow envelope from Australia.  Yup, my XP-G 2 emitters just arrived.  Being the impatient type, I had already set aside a light to upgrade when they arrived.  15min later my MG P-Rocket xpg has been upgraded with the xpg 2.  This light was an ideal choice due to having a constant current driver already and a well designed reflector for this emitter. Here are the before and after numbers:

Tailcap(mA)StockModded
    Low10ma10ma
    Med440ma440ma
    High1400ma1400ma
Lumen OTF StockModded
    Low 15L 17.6L
    Med95.7L108.5L
    High 276.7L 332.8L
Lux @1mStockModded
 8,40013,000
   

This is very encouraging, and I can't wait to get these new emitters on the bench and see what they can do!

Nice work Match. I hope the postman doesn't have burn marks on his fingers from a package being ripped out of his hand. The top end figures look real impressive.

My current and or voltage measurements are only relevent to anything that I measure.

I was under the impression that the tighter 115 degree emission angle would be worse for a reflector? Or is the upped efficiency over the original emitter enough to compensate?

So, stock is XP-G R5 vs. modded XP-G 2?

What tint did you get, did it match what you ordered? How is the quality of the tint?

These are the 1A tint R5's from cutter, which is what I ordered.  The tint quality is pure white, with no discernible color shifts near the edges.  I'm very happy.

Very interesting and good job Match.

I have a question though, shouldn’t the new XP-G 2 be S4 bin since it puts out 20% more light than an R5?

It would be good to know how hard it can be pussed in Amps to use it with aspherics for throw.

In any case, a 20% more output than XP-G is a good thing.

For aspheric set up.
20% more out put.
5-10% out put in term of narrow beam 125 and 115 degrees.

I plan to drive with 6×7135 V2 around 2.28A + 67mm aspheric.

I assume around 150,000+- lux and 4xspot compared with XR-E .

BobK,

  I think you'll like them.  Once I see how they perform at 2+ amps they may start replacing a few of my xm-l's in certain lights. If I can get close to 600L otf with double the throw of an xml, that'll be perfect for a few torches.

Match. I do not have any idea how this would work hence the question. How would this LED work in the likes of the HD-2010?

Honestly I don't know for sure (I don't own an HD-2010...sad I know).  My guess would be similar to SashiX, in which the lux would definitely increase, but by how much I couldn't tell you.  Not every reflector works well with emitters other than what they were designed for.  It could be a ringy horrible beam, or it could turn out to be the combo of the year.... Guess we won't know till it's tried.  (My money is on the latter!)

Thanks Sashix and Match. I dont really want or need a pencil beam light but if all goes well the weekend looks more exciting than it was. Match This will be going on a copper pill similar to my HD-2010 2 x 26650 battery mods http://budgetlightforum.com/node/11255 . What amps would you start at. I would be using a kd 3040 amp or 2.8 amp 7135 driver. I would have to take of chips to reduce the amperage.

The perfect white tint is one of the most exciting “features” for me Smile After 2 years “playing” with various emitters, I can clearly say that premium Q5s have the best tint Love Pure white without any “strange” hue. So, if this emitter has similar tint, I’m in Silly

Here you go, perfect driver for that emitter Silly (I can be wrong though)

SashiX read my mind.  I was just about to suggest a similar one.  With some good thermal paste and lapping the star to the pill it should do well.  Keep us posted!

The white tint is awesome but it's the potential for some throw with this emitter I'm excited to see.  Correct me if I'm wrong but I don't think an XP-G would do well with a flat bottom reflector like the one used in an HD2010.  They seem to work better when the reflector angles in tighter around the emitter.

Or, maybe I have it backwards.

for pointing out that it may fail, party pooper Wink. You have made me sit back and have a long hard think about it. Yep, after 10 miiliseconds a decision has been made. I will mod the stock pill as a mule first before getting carried away. I have picked up a couple of 1D tints this afternoon. I have no experience with this tint so it will be a new experience. On the color chart it appears very similar to the 1A tints. Do I apologise to Foy? I would except I think he is busy with his two hands. I'm not sure on what though.Embarassed

Unpleasant though it be to consider, the possibility of Foy being wrong is close and ever present.
