Is there any buck driver out there or something that can drive the 1mm boost HL to 6amps constant?

Dobro jutro Neven,

I am interested into your Q8 boards with OSRAM KW CULNM1.TG. Can you please help me find out some information about the LED?

  1. What LED is this exactly? Is it a "small 1mm² OSLON BOOST HX or something else? It is nowhere to be found on OSRAM's website. They only list the 2mm² KW CULPM1.TG (Boost HX).
  2. Do you have a datasheet for the KW CULNM1.TG LED? I would like to know more about its maximum current sustainability.
  3. Will you be offering the Q8 MCPCB with KW CULPM1.TG (Boost HX 2mm²) in the near future?

It's interesting that the big 4040 Boost HX (2mm²) can sustain 6.6A of current and ist rated 20.1W of power while its "predecessor" the 3030 "White Flat" 2mm² CSLPM1.TG sustains 5A but is rated with only 4.38W.

Hvala vam!

Thomas

LED is not available on OSRAM pages probably because it's already discontinued, I added datasheet link under product listings, here is the link:

3. If I manage to get small quantity somewhere, or become rich enough to risk and buy whole 2000pcs reel, then yes:)

Why was the led ever made if it is discontinued so soon already? Is that an assessment error from Osram or calculated in beforehand?

"Due to low market demand the OSLON Boost HL KW CULNM1.TG has reached its end of life. "

This can be found in official document:

https://www.mouser.com/PCN/Osram_Opto_Semiconductor_1_cip_OS_NFND_2018_008.pdf

The main purpose of this LED was (it seems) automotive headlights, but it looks like potential big customers did't like the size of LED package, for whatever reason, or cost.

Thanks, interesting. There was a name for the KW CULNM1.TG in this document btw: Oslon Boost HL

How about the HX ? Is that being phased out already as well?

Thank you Neven! I certainly hope you get rich soon and do us the great favor in buying a complete reel of Oslon Boost HX LEDs. :D

The Oslon Boost HX 2mm² is still advertised on www.osram.com, so I assume it's not being phased out already.

Personally, I think the 4040 KW CULPM1.TG would be even better for using in the Q8. But it's hard to resist the CULNM1.TG. ;-)

Assembling the MCPCB into the Q8 should be comparable to the Luxeon V board, though.

No, it’s fine.

Hi L4P,
have you contemplated put Boost HX in your store for preorder?
That way people could pay you in advance and, if it is reached the 2000pcs goal, you could purchase a reel.
I don´t know how much interest is on that LED, but SST-20 GB reached 1000pcs in about a week.

I would probably buy 20 pcs of the Osram Oslon KW CULPM1.TG (2mm² Boost HX), so 1% of the MOQ is already reached. :stuck_out_tongue:

Based on CULNM1 sales data, I don't think there would be enough interest.

Order # L4P2066 received. Everything is supremely decent. Packaging, delivery time awards all praise.
Where can I read about the correct switching of thermal control, wire wiring, as well as setting up the driver?
Respectfully ….

I think people were anticipating the 2mm boost way more than the 1mm boost.

Why not start an interest list?

I could help if needed. :slight_smile:

Yeah, people are conditioned for Group Buys around here. I think if an interest list were started, in a new thread, and given enough time, you could easily reach a couple thousand or more, especially considering that the Boost HX is one of the most highly anticipated emitters in recent years. I’m not surprised at all that the “lesser” version didn’t get much interest.

I’m sure I can get Vinh of Skylumen to buy a ton of them. He goes through the non boost 2mm White like a kid at a candy store.

I know I’d buy some myself. It has to be a high bin though.

Hello I would like to purchase six LUMINUS SST-20 4000K 95CRI LED (SST-20-W40H-A120) – Bare and two L4P 3XP Triple 20mm DTP (Direct Thermal Path) Copper MCPCB. I wondering if you offer a flow service to flow the leds onto the board? Thank you!!

I believe this listing is what you want (nevermind his lazy URL naming he does good soldering, lol)

Thank you!’
