@adam7027

Do you recommend using LD-A4 for relatively small hosts?

I would like to make Jaxman E2L builds with this driver, and triples of different white emitters (Luminus SST-20 4000K 95CRI, Nichia 219C 90CRI, Samsung LH351D 90CRI).

How safe is it to use 9A or 6A as maximum current for this host and the above-mentioned emitters?

I did some reading back to tread page 15, and found this detailed description.

Now I am sure, that 9A would be clearly over both host and driver limits. I just would like to ask, that would I be safe with 6A as max. current in Jaxman E2L host?

[led4power]

I don't know what do you mean by "safe", it could be safe to use that host at any current, only difference is lumen output and time until host reach temperature that will trigger OTP protection.

E2L is an awesome host and spreads heat throughout entire body (good) but its only a matter of time before it steps down. I have all 3 leds u mention with FET driver in E2L and 1 S2+ XP-L HI with Cu pill and LD-B4 and mosx+FET. They are all really nice.

Hi Neven,

is there any chance to buy the Oslon MCPCB with the Oslon Black Flat soldered to it (at additional cost for reflow and material)?

https://led4power.com/product/mosled-extreme-mosx-ceramic-insulation-osram-oslon-mcpcb-20mm/

I plan to have the XP-L HI exchanged by the OBF in the BLF GT Mini but I'm not sure how sensitive this LED is when doing the reflow by oneself. Is there already any valid information when the successor of the OBF will be available?

Thank you very much!

Cheers,

Thomas

See What did you mod today? - #4138 by djozz
I’m not sure if he used Mosled or MosX.

[led4power]

Djozz used DTP board, black flat has very high power density so mosX is not as good as DTP at these power density (W/mm2) levels.

Any progress on any of the new items that you are planning to release?

I meant it regarding the driver plate. But as the head of a 8×7135 Convoy S2+ can reach temp easily above 70-75°C in still room temp air in less than 15 minutes, probably 6A with the E2L host will mean only about 3-4 minutes ‘turbo’ usage before driver protection shutdown mechanism at 105°C will kick in.

Limited qty of subZero switches should be available in 2-3days,spacers too, full kits 2-3days after those.

LD-A4 can handle 6-9A in triple setups,but only with good thermal path between driver's FET surface and flashlight body, something like S2+ thermal enhancement kit from my store would be required.

LD-B4 doesn't have these problems, but mosX boards must be used, and problem with JAXMAN host is that it uses non-standard ~19mm PCB diameter, with max. allowable diameter of ~19.5mm, at least that is what I've heard. Maybe new version of hosts allow 20mm pcbs?

Usually you can sand down pcbs by 0.5-1mm, but with mosX is there is high chance of short between copper top layer and core.

[djozz]

The E2L still does not allow 20mm boards.

What about the high-current drivers? I want to order everything at the same time.

[led4power]

Full kits will include drivers.

Any chance you’ll get alu DTP boards in the future?
