Can the person who sent me a helmet complete with Dragon lamp power bank and spare be so kind as to contact me and tell me who they are and what the fault is. I can only see that the batteries needed charging.

Anyone sending in an RMA etc should please stick some kind of note in hopefully with sale number and name, and a description of the fault. My Buddhism and martial arts skills does not give me psychic powers.

Just for the fun of it, I have decided to make my friends on aditnow, insiders to what is cooking in the lab.

What I have is the next generation of super bat cooker.

Anyone who was on one of my trips at NAMHO 2019 will have seen the 'prototype' lamp i was using.

It s a 16V sealed rechargeable based on the Scorpion design.

The power of the beams has been increased since NAMHO.

A few features:

300 lumens for 27 hours then a slow death of up to 3 hours, 160 lumens for 2 days, full power now 9125 lumens.

Beams max at over 4500 lumens, floods at 4600 lumens.

4 cell power bank, sealed rechargeable, charges from a variety of chargers (19V laptop, Laptop in car, 16.8V Li ion etc), flashing red charge indicator, weight 360 grams. (Scurion 4 cell aluminium dive pack is over 300)

Innovative eye level status monitor, flashing red lamp overheat alarm and blue battery level indicator mounted on the base of the lamp.

Transport lock, toggle switch with split pin prevents switch moving inadvertently to 'lamp' position.

Yes. I have dumped the piezo in favour of a flashing red LED.
What is interesting is that I had to reset the trimmer potentiometer because the LED was flashing far to early. I was in the belief that I had set the alarm to 65C because I could not hear the piezo as it was coming in at a pitch above my hearing level. Wrong
Its working perfectly now and is part of the eye level display on the base of the lamp. This feature is probably a first in lamp design.

It was and still is an LM 393 output so if any geeks have useful comment I will be interested.
