The idea to use Nichia NVSWE21A (sm453 r9080) was based on hope that it would be possible to create design of Sofirn’s DCF01 inspired by Muyshondt Beagle MK. I and McGizmo ls20.
The design was sent to Barry and his response was:
‘What I can say is to get high CRI E21A is not a issue, Sofirn will handle it.
One main led surrounded by 4 E21A can be done but that make it a expensive light’
I asked how much would it cost and Barry promised to come back with a rough price.
Unfortunately Sofirn is worrying that it would make the flashlight too pricey for possible BLF Group Buy and later for average customer.
For this GB to happen it needs to secure 500 pieces in orders.
Same happened to the idea of taking some inspiration from this camera (Would be nice to have a rotary switch):
Therefore quest for a shape that would allow this flashlight to be manufactured at reasonably price continues.
As this flashlight (with it’s accessories) is intended to be really nice gift bundle the need for a nice feature emerged.
Maybe… a battery indicator like the one below?
And than… I stumbled on ttever3’s mod:
Barry’s reaction: ‘To add a lcd display to show how much juice left is a good design for muggles.’
It’s hard to find a muggle who doesn’t prefer USB charging and that’s one among other things that will make DCF01 a perfect gift flashlight.
We are building here something unique, second to none 2AA head-turning flashlight. The sort of thing that everyone deserves, but most people won’t buy for themselves — therefore a perfect gift. Great for any outdoor adventures as well as for all kind of indoor activities. By putting OLED we already made it more appealing to potential customers. By adding USB charging convenience (with information on display of time remaining to fully charged) we are making their choice of proper flashlight even easier for them.
The question will be asked by many:
What happens when someone makes the mistake of trying to recharge the AA primary batteries inside the light?
Well… First of all, there will be rechargeable batteries in the bundle/kit and rechargeable batteries recommendation printed both on the box and inside manual. Possible leakage or explosion from overheating will be shown in pictures in manual and put in CAPITAL LETTERS.
The flashlight will be designed to work on alkaline batteries, but ONLY in emergency situations. It will be not advised to use alkaline batteries on daily basis.
Any type of power source requires intelligence to be used safely. It really doesn’t matter if it’s Alkaline, NiMH or Li-ion.The risk of someone accidentally charging an alkaline in this light is not any more than someone accidentally charging an alkaline in a stand alone charger. If it’s really that big of a risk, there won’t be any consumer AA chargers on the market. I think warning stickers and labels should be adequate.
At the beginning there was an idea of removable pocket clip. Something like this:
But than I heard of Frelux Synergy 1 and the more I’m thinking about it’s clip the more I like it. I also like a small width of the knob.
Another light that can be used as an inspiration is Acebeam UC15: https://imgur.com/a/1IoGTyC
We could change it a bit and use a clip and a knob similar to one used in Frelux Synergy 1:
