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

Yes, you are correct, I figured they must be using a buck driver with V+ regulation or something. I just happened to get a notification yesterday for this thread and popped in. I know nothing about this project at all.

Please add me to the list for one lantern. Thanks…

I added Flash-O-Maniac at number 895 on the interest list.

I did the two-part video tonight on the talk about the BLF lantern, will be uploading it to my youtube channel as soon as i get a good data connection!

What’s the name of your YouTube channel? Could you post a link to the video in the forum?

Yes please can we get your channel info?

I will post the link here tonight when the videos are up. :slight_smile:

:beer:

The Wifi location i am in right now is horribly slow, videos say the upload time will be some 5 to 6 hours. hopefully they will be online by tomorrow.

Brutal. :person_facepalming: Hope you have something enjoyable to pass the time, or maybe it will finish while you sleep.

Interested.

Pidro added to the interest list at number 896

- Part 1 and Part of the video is online! ignore my fast-talking east coast Canadian accent & beginner video recording. *lol
hope it helps explain a bit more of the lantern design & info.

here:

Thanks, DBSAR. It’s great to see the lantern and hear about it on video. Nice work!

The video nicely illustrates your design considerations. :+1: Looking forward to part two.

Seeing your prototype in video form has me even more excited about this project. :slight_smile:

Thank you DBSAR for the Video and the informations!
And your Canadian accent is ok. I understand the most of all :smiley: :+1:

Where did the Q8 diffuser come from DB? And does it fit over the tube, so that stored with the Q8 it doesn’t take up much more space? Sorry this is a bit off topic.

Thank you for the detailed video! This project is by far the most interesting I have seen on BLF. This light will truly be better than 99.9% of the lanterns on the market.

I have some questions:

  1. Will the bolt that connects the head to the body be made of stainless steel?
  2. Is it possible to make the LEDs in the switch darker? It would be perfect if they dimmed down together with the light.

I know I’m not DBSAR of course, but I can answer the questions.

- It could be made of stainless steel, but using aluminium would be much better in terms of weight and cost. So it is probably going to be aluminium in the production units.

- Yes it is possible. You just need to swap out the LEDs for ones that have less scotopic light content, meaning less blue, meaning orange LEDs will probably be used.
You can also use higher value resistors to make the LEDs dimmer.

You don’t see aluminum bolts very often because they are very prone to necking . I would rather see steel or stainless used for this component, but cost is obviously a very important factor. That decision will be up to DBSAR and the manufacturer at the end of the day.
