Today (25/5) my long anticipated Λ-17 lantern has been completed. It is a hotblast Frowo 420 made in GDR (50-60s model) with a wooden globe lifter and logo on glass. It employs a λ-series circuitry, have 4 cell 18650 capacity and can output 500 lumens. It comes with a reflector.
The other lantern made along λ-18 is a same model Far East that was treated differently. It has a clear alkyd coat varnish (bare metal finish) and employed a newer design K-series + circuitry inside along with GU4 new socket elements Can take either stabdard XHG cree leds element or lumileds 90 cri leds. ( higher light quality a bit less efficient)
Today (23/5/2016) the Λ-20 lantern of the series were completed. It has some different features in comparison to previous models as a GU4 socket luminus element (smaller footprint) and circuitry mounted on cell holders inside allowing less cables used. Metal semi de-rusted clear laquered
two more lanterns, both Chalwyn Far East models with embossed the logo torch on their shades were finished today (22/5) λ-18 is primed then acrylic painted deep black matte. λ-circuitry is used insede. GU4 socket luminus element – new – is used.
Its a redesign of the standard Barou’s ® K series circuit. The somewhat large blow fuse was replaced by electronic latch fuse (triggered over 1.8A at 10msec) that needs no replacement to reset. Limits to its operation apply as the higher blocking voltage is 35V. In contrast the older fuse can shut off larger voltages as 110 or 220volts but the cut off time (even though of the fast blow type) rated 3A is around 50-100mS achieving momentarily 20 / 40 or more Amps. (bad for circuit) Generally the new circuit is leaner, less prone to errors and somewhat more efficient (+ a pleasure to eye also 🙂
In the latest and best portion of the August, two small sized MEVA 863 models have been completed. One black, enamel painted spray and another Red that it was named “ΝΕΔΑ” That latest batch came with some minor improvements in cell holder and circuit fastening.
Inspired by the lantern retrofication work and “make per wish” potential, Bryan from Colorado send me two great brand new Dietz Champion lanterns to work with. I was really impressed by those towering beasts! After exchange of ideas and discussion, he set his mind on having: Fully dimmable light output from 30 or so lumens up to 900-1000 Lm Warm white 3000-3200 K External 12v power. (no batteries inside) Safety no 1 priority under any circumstance Primary function would be those lanterns to serve as room lights and secondary in case of emergency or camping etc to be used from a car battery! Voila! 🙂 Photos:
Chassis restoring and rust protection for now. Work in progress
