The SAE J581 Aux High Beam Thread

The max uses an expensive chip. I think Osram only produces limited quantities of the CULPM1.tg (boost HX 4040 footprint chip) as compared to their cslmp1 and cnlpm1 chips (the same 2mm^2 as the boost hx and 1mm^2 die, respectively). The cUlpm1 is a rather expensive LED, in comparison to the luxeon Z-ES (Sport) and Cree XPL-HI (Pro). So going from 4 leds, to 9 per lamp would be a pretty significant increase in price. The performance increase in a smaller form factor, going from the larger die of the XPL-HI to the smaller die of the culpm1 is worth it, as it focuses better, meaning you get the benefit of higher output and increased focus for their primary street legal lamp, as a Fog lamp.

I could see them eventually switching to the osram cslpm1 LED, the boost just has better thermal characteristics. But that also means yet *another* pcb design, retooling and setting up for a 3x3mm footprint LED. If anything, they may be looking at Cree's new XP-P led, which should offer "similar" performance to the 1mm^2 cnlpm1 osram LED, but in the same 3.5x3.5mm PCB arrangement as the XPL-HI, meaning they would have potentially one board design with a few component changes, to provide the lower output/higher focus+intensity of the Luxeon z-es and the higher output of the XPL-HI. However the xp-p is new to the market and cree does not appear to have plans to offer it in much below 5000k color temps.

What would solve this is if Cree were to offer the XP-G LED in a domeless "HI" format, as the higher efficiency bins of the XP-G2 offered similar surface intensity as the CULPM1 led when driven similarly (and de-domed, which a manufacturer like DD is not going to do, due to decreasing the lifespan of the chip, as well as potential for lots of damaged chips that must get tossed), it has a nominally 2mm^2 die (that is actually square, as opposed to slightly rectangular with the cUlpm and the cSlpm1). Given that they've just introduced the XP-P, I don't see them trying to market such an emitter yet though.

 

I'm hoping for an SS7. Current optic sizes will put this in about a 5 inch circle.

 

Either arrangement, 3x3 or 7 will be about the same overall size. Both will be tricky, from a drive circuit, having to either boost to 21v/27v, or buck to multiple parallel strings of 9v (if 3x3 arrangement) from whatever input range. The 2x2 arrangement of the SS3 pods made for a nice buck only arrangement.

 

@memario1214

SS3 max driving ordered. Haven't figured out how I'm going to mount them yet but might as well save a few pennies while trying to figure it out.

 

This harness does have to right connector for the SS3 pods doesn' it? No reason to pay DD $50 for theirs when this one is $21

 

Since DD confirmed the price increase doesn't come with massage afterwards I'll save a few bucks.

Thinking out loud, since I want to trigger them off the high beams anyway should I just get the BD hi beam tap harness and switch (or get adapters) out the WP plugs?

Yuk on that switch though.

 

wasn't planning on using it. Either tapping the hi beam or putting on a wireless receiver and using one of the homelink buttons on my sun visor.

But, what would you recommend?

 

I'm a fan of the OEM small size switch in a blank but many of us run out of those super fast. It might be nice to have independent control, though a rocker would really be ideal, on, off and auto (based on high beam). Anytime Backup Camera has such rocker switches which fit the Tacoma.

 

If I had any of the Japanese brands that have blanks in switch panels your idea would be perfect. For us F150 guys the most bestest solution is adding the 6 switch panel from the Raptor nut that is a very high dollar solution. Having 2 unused homelike buttons available tied to wireless switches seems???? like a good idea.

 

Thank you, you da MAN

 

Idk if this is the proper thread for this. But any chance @memario1214 or @crashnburn80 have seen this light bar by Front Runner/Osram?

They have a 22" with the ECE certification

 

I just stumbled upon it. Be super curious to know the specs on it. I’m a big fan of the Front Runner stuff.

 

Yeah it looks like they released a whole bunch of lights recently. They have all sizes on there.

 

I have not seen that specific bar, but it appears to use the same mini reflector technology with an up-firing LED that Osram uses in their ECE bars. I'm not sure what they mean by "Double ECE R112 compliant". That bar seems awfully large to be ECE R112 compliant.

See Osram's explanation of ECE R112 here, underneath their driving light bars: https://www.osram.com/am/campaigns/ledriving-working-and-driving-lights/truck_ledriving.jsp

The Front Runner bar has this line under the specs, which makes me think they are measuring 2 separate outputs on the bar as 50 + 50, implying it would be ECE R112 compliant if you didn't use your factory high beams maybe:

• Individual installation is possible due to the FX1000-CB SM's double ECE certification (ECE-Reference: 50+50; R112).

Regardless of compliance, it is an interesting looking product and the first I've seen in that large of a format. I haven't yet tried our Osram/Sylvania's reflector based light bars, but the design in principle provides far more control than forward facing emitter bars, meaning you can get higher output intensity with lower power due to better focus similar to the reasons why KC's Gravity and Diode Dynamics TIR optics work so efficiently. The same design idea is used in many OEM automotive LED headlights, including the 3rd Gen Tacoma, though typically automotive headlights will use larger LED reflectors which offer more control and efficiency than smaller ones.

Edit: Also definitely the proper thread.
