R-bin 1 Watters becoming more common

Zman · Apr 18, 2005

I read the announcement last week that lumileds was upgrading the ratings on the 1 watters. Today I'm noticing the Shoppe has R bin 1 watters RYOJ!
I also did a search for R bin from Yahoo, and Tektite is advertising The Excursion LS1 with an R bin luxeon!
Pretty cool if you ask me...
Your thoughts??

Recently I found RX0H from TM-306X ( Q-I ), dang BRIGHT !

chevrofreak · Apr 18, 2005

RX0H would be a GREAT bin if you ask me! Very white.

I think R bin is going to breathe new life into lots of 1 watt applications. I have an arc ls or two at stock current that might benefit.

chevrofreak · Apr 18, 2005

Is R bin the cutoff point between LuxIII and LuxI then?

smitty244 · Apr 18, 2005

I would think so at least for the time being - I guess it is only a matter of time before Lumileds updates the Luxeon III 'typical' specs to the T-bin from the S-bin (75 lumens vs. 65 lumens). I ordered some Lux Is from Future and got RX0H, I have some more coming tomorrow so I can update with what they are... I think they are the new standard Lux Is since Lumileds updated their specs to 45 lumen typical - not a bad deal at $6.25 or whatever it is at Future!

I had SXOJ's in some of my Nuwai TM115's with 2 stage switches.
Even low beam didn't go green at all with this *XO* tint bin.

i thought 1 watts day was over? i was thinking 3 wtts was so much better specaily with the u bin comeing out .am i corect?

chevrofreak · Apr 19, 2005

I found a QX0H in a Costco luxeon light tonight, good lord is that a nice LED. I measure 2100 lux!

Prepare to drool

raggie33 · Apr 19, 2005

wow chevro did ya buy chance see what it is drawing?

chevrofreak · Apr 19, 2005

hadnt yet, let me bust out the multimeter.

Wow, 820mA is going to the circuit /ubbthreads/images/graemlins/ooo.gif

raggie33 · Apr 19, 2005

damn thats pretty steep for a 1 watt

chevrofreak · Apr 19, 2005

Indeed /ubbthreads/images/graemlins/ooo.gif

Almost exactly the same as a MadMax+/WO. /ubbthreads/images/graemlins/tongue.gif

Lumileds has been sitting on a number of lab breakthroughs, and now that competition is heating up, it's not surprising that they're upping the numbers on their current products while they ramp up for production on new product lines utilizing said reakthroughs.

I'd be hesitant to pay premium for bins formerly classified as "uobtanium" since better product is expected this summer.

IsaacHayes · Apr 19, 2005

RX0H! Wow, perfect flux, perfect color (I say X0/W0 are great), and perfect Vf! (uber low!) With a H Vf you either get insane runtime from a constant current circuit, or extra current to the led with a voltage boost circuit.

greenLED · Apr 19, 2005

/ubbthreads/images/graemlins/stupid.gif please enlighten the noob here, why are R bins so special?

StoneDog · Apr 19, 2005

R bins (especially with "H" Vf) are PERFECT for lower-output situations. Why use a Lux3 on a BB400 or MMLite sandwich, for example, when the extra heat pathing(?is that a word?), etc aren't needed and you're running at less than half of spec?

There is some speculation that a "T" bin Lux3 at 400ma isn't any brighter than an "R" bin Lux1 at 400ma. The same holds for "S" bin Lux3 & "Q" bin Lux1.

If I could get RXOH under $7 a piece I'd jump on them!

I think it is because they are 40-52 lumens per watt (still 350mA) which makes them almost twice as efficiant as a Luxeon III (which is around 25 lumens/watt typically) - the H-Vf is nice because it is 3-3.25 volts too

Zman · Apr 19, 2005

GreenLed--I started the thread because finding an R bin used to be very difficult. Semi-unobtainium /ubbthreads/images/graemlins/wink.gif
