No, I do mean relative numbers too. Even small black things inside integrating spheres affect the amount of integration noticably, and a huge black thing like the BLF Lantern inside a relatively small sphere will effectively kill useful integration of the light output. (no good integration means that what we measure is not total light output, and comparisons can only be made with light sources with the exact same beam. While a different beam is what you want to compare here) It will be a little better than just leaving the sphere out of the setup and just position a luxmeter next to the lantern, but not much better than that. Making the lantern shiny (or even better matt white) enormously improves integration so that your measurement actually somewhat represents total light output and so you can make comparisons. Btw, also baffling the detector against direct light from the lantern would make integration better.
It is not that I want to wish to come over as some know-all, but measuring light comes with some pretty annoying rules and in theory design decisions could be off because they are based on too rough comparisons, and that would be unfortunate.
As planned yes, as i have to know the characteristics, dimensions, and abilities of the production model first for some of the accessories. The various accessories will likely include, or variations of,
- a brim-type upper reflector.
- a side directional reflector.
- soft padded carry bag.
- 12 to 15-foot charging cable, (heavier gauge wire)
- high capacity 3500 or 3600mah cells.
- a snap on wide base for uneven surfaces.
- a thread in powerful base magnet.
- a hard case to fit most accessories & the lantern.
Wall hanging adapter bracket
Other possible matching accessories may be added, including,
- 10-watt or 12 watt folding solar charger panel
multi-voltage charger power adapter, (12 volt DC, 120 volt AC, 240 volt AC)
Some of the accessories i am already working on with testing on the two prototypes i have.
Reminds me of an article in some electronics magazine some 20ish years ago about dark emitting diodes. This is the first picture of them I’ve seen since then!
I have noticed that the BLF LT1 Lantern project has brought in a large number of new members over the last year! I’m guessing because its opening up a project that is needed to fill a gap in the portable area lighting/lantern market that had little to offer when compared to the features & performance this light has. The increase in interest is staggering since Toykeeper began posting the first real photos of the factory sample prototype. In the mean time while i am eagerly awaiting for the arrival of the sample test unit so i can get to work and begin the vast testing and picking the bones out of it, I will have a drink at my bar with the original two design prototypes, as they await for their production version to be evaluated against.
