*BLF LT1 Lantern Project) (updated Nov,17,2020)

Please if it is stil possible ,add me on the list for one…

I’m really looking forward to this project coming to fruition. Great work from everyone involved.

For the emitters, you might want to consider the Oslon Square 2700k 96CRI. The tint is absolutely gorgeous for the color temperature. No yellow/green. The one sold on Ebay is a slightly rosy 6U tint bin and a high flux bin for the CCT and CRI.

Additionally, E21A 9080 tint mixing would be a really good option.

For Oslon Square high CRI leds the tint bins must be monitored closely, I had many green leds from RS components an Mouser before.

We may have to consider that option, as we discovered the Samsung 351 series LED are hard to order by the manufacturer. If Olson makes them in both 2700K & 5000K with the same foot print as the 219, XP-L, etc. that would be perfect as long as they are more efficient Lumens-per-watt than the 219 series.

Definitely want to avoid any greenish tints.

I just got the last batch from that eBay seller :smiley:

You just need to buy the right tint bin. The 6U is a really nice tint bin. No green at all.

Djozz and DBSAR, if you want, I can mail you a few pieces to test.

You’re right, it’s gone. The link now leads to a similar but inferior product. For the lantern project if interested, Sofirn can contact the Ebay seller or maybe even Oslon directly to see if they can source more of the 6U tint with MQ flux bin.

That would be great to test for the BLF lantern project. (as were discovering the Samsung 351 series is harder to order apparently that the manufacturer was telling us, and need to find a good replacement LED type that has good efficiency & tints for lantern use. (send me a DM for more info)

Love the idea and truly appreciate all the hard work that went into the project.
Wish I was 1/10 as handy or useful…
Darn it, I think me wants one, why? just because…how much?

Interested if its compatible with the BLF Q8.

Perhaps the battery tube, but probably the rest will be different. Just what kind of “compatible” are you looking for? I think since there’s now such a thing as extension tubes for the Sofirn Q8, it would be nice if the tube of this light were made compatible with those. The “stock” Sofirn Q8 battery tube won’t work to be extended. So it must be replaced in order to add the extension. Therefore, the “extension set” includes two tubes and two battery holders. If this lantern’s battery tube were to be already made like the “replacement” tube, then just a single extension tube and battery holder would need to be bought for it if someone wanted to extend it. :wink:

1116 Tomogchi
1117 Tomogchi
1118 brasilchris
1119 AguassissiM
1120 Doctawho

AguassissiM, no firm price yet, likely around $40. I think I may have provided lower estimates in earlier posts but the reality my SWAG is based on something I read in this thread a long time ago. Sofirn has not provided any sort of price estimate at this time.

Doctawho, not exactly sure what sort of compatibility you are looking for, but the design is leveraged heavily off the Q8. Put you on the interest list, it is not a committment to buy, just trying to gauge roughly how many lights will sell out the get go for Sofirn.

OP list updated :slight_smile:

Great because this means that the nichia optisolis can be considered as a candidate…a true ultimate lantern should use those LEDs or equivalent.

Thank you for quick response, much appreciated.

Interested. Please put me down for one.

FYI, Digikey does have the LH351D in 2700K and 5000K.

But they can only be ordered in quarter bins (can’t choose between above or below BBL), as far as I know.

I am interested in one.

Thanks for all the work so far.

Is there anything that an enterprising community member can do to help this project along?
