Mm, I dont know about that. I am moving into sensible lamps for really sensible people, I have heard that there are quite a few about, but not round our way.

It appears that sensible people are increasing on UKC, so maybe a New Year coup? Who knows.

Anyway, have a good Christmas and New Year, just try to convince your wife or partner who I am sure is very sensible not to encourage the youngsters to take their dad as a role model.

Take care
Roy

Hi again
I have just had a letter from the Patents Directorate. It seems that my patent is approved for the heat conduction and dissipation system as used on the Trigon. Finalisation Feb 2018

There must be thousands of Oldham headsets in stock somewhere, this system would convert them to a good recreational lamp.

More news. Scorpion face plates arrived this morning and have been finishing off the prototype X_12, photo probably tomorrow with the daylight.

Well here is the finished Scorpion prototype, ready for extensive testing.



(click image to open full size image in new window)

Fully GoPro Compatible
Max output 3500 lumens
IP 68: 5 metres waterproof
User friendly 2 mode groups of 3 modes from single toggle switch, high range and low range.
Switch up, on and off: 300,1000, and 3500 lumens
Switch down, on and off: 40, 75, and 160 lumens
Memorises last settings so ability to switch instantly up or down to pre-selected modes.
2 sets of 3 LEDs, 2 beam and one flood, power divided equally.

In all modesty, a lot of thought has gone into this. Down to the choice of the circular front lens direct bonded to the body. Its 60mm outside diameter bezel will take standard accessories like a diffuser for photography. It will be available with a wide range of GoPro accessories and will mount on anything beside a helmet, eg a tripod.

Weight is 230 grams, other versions will be lighter.
Price in the range of £200 - £250
Other versions cheaper.

Power bank solution is still being developed. I am testing with the Lynx X12 2070 version which unfortunately is nearly 400 grams. I have a lighter 18650 pack which weighs 266 grams but its only 2600 mAh as it has high discharge cells. I will test the lamp with high capacity 3500 when they arrive, as I am currently out of them.

New: The Dragon EX

Same as D1800 but with following changes to Spec:

Analogue design with two simple modes from each switch throw,

Water resistance raised to IP 68 – 5 metres submersion.

I have no intention whatsoever of discontinuing the Dragon as it’s the best worklamp I have ever used weighing in at a mere 125 grams. That, and its small form factor make it the ideal lamp for digging projects and general usage where size and weight are an important factor.

Looking at returns I have become aware that I have had more Dragons back than any other. Looking at the lamps themselves there is every indication that this relates to the type of use rather than any inherent defects in the design. Indeed, I have just had one return due to a switch failing on the upper position. Indications are of the ingress of water at the switch, which although of German manufacture and IP 67 rated (1 metre submersion, 30 minutes) had suffered from water ingress causing it to fail in the upper throw.

Another literally looked as though it had been dragged along the ground off the back of a Landrover on cross country exercise.

I have come to the conclusion that IP67 is just not good enough for hard usage. A customer had slight water ingress on an X2000 a while back in a water fall under flood conditions where it was not possible to stand, he had to crawl on his belly. This exceeded IP 67 standard.

As a result of all this I am looking at upgrading water resistance to IP 68 - 5 metres submersion on the whole range of Scorpions as they are developed, with a 50 metre dive model as an option. Main issue with the whole range is the fact that at greater depths water would be forced up inside the cable from the plug, so dive models will be integral with the power bank which will open up for charging.

For some time I have been shipping lamps with upgraded IP68 glands, the last Dragons to go out had rubber boots over the switch and threads sealed to raise the water ingress resistance. The boots may well split under hard use but they are easily replaceable by the customer, the switch would then default to IP 67, and I may be including a spare in the future.

The Dragon EX is named thus where “EX” stands for “Extreme Usage”. This model is down to two modes from each switch position, down is standard, and up is high, perfectly logical. Downlighters have doubled in power and common to both settings.
The lamp now is completely analogue, no PIC. Standard is powered form a simple liner driver, high from a straight switch mode driver. Downlighters operate from a liner driver plus a Schottky diode to prevent the standard mode feeding the high through the downlighters. The switcher is directly heat sunk to the copper thermal conductor which directs the heat to the outer casing.
The result is simpler internal layout with less to go wrong, and more importantly, more room around components, but at the expense of some functionality. I have to see how this is accepted.
Unfortunately there wont be a dive model Dragon as the front glasses are direct bonded on the inside, with extra support from the abutment of the reflectors. For diving they need to be on the outside so pressure forces the bond rather than against it.
Nor a Lynx due to headset design.

Hi Roy. Sorry if you've already answered this question but the new Scorpion looks brilliant, do you have any idea when it will be available to buy? My girlfriend is after a new lamp so I think I'll treat her to one when you start shipping. IP: 86.17.132.208

I want to be able to launch all models simultaneously, The X12, X8 (same config as current X2000), EX_Basic, and the Dive.

I have a waterproof battery case for the dive, this model will be same as EX_Basic but a double beam same as X12 rather than a beam and flood. The EX_Basic will have IP 68 - 5 metre button switch, delivery on the 15th from RS Components, while the Dive will an (expensive) IP69 10BAR.

Both these will use same electronics as current Lynx X_Basic so can be supported by a 2 cell power pack. But use XP_L emitters for a total of about 1500 lumens.

Looking good so far, just confirmed that 3S of the best 3.5AH cells will support the Scorp X12 at full power throughout most of the discharge range, so weights continue to fall.

Only just on my feet again today, been virtually flat out on my bed all week with the mother of all chest bugs. People take warning, there is some real nasty stuff about. I caught mine at Sainsbury's of all places.

First shipping probably March

Thanks for getting back to me so quickly, I'll keep my eyes open for more details in March and hopefully get one of the first batch. Glad you're recovering, all of my family had it over the holidays but so far I've managed to avoid it. IP: 86.17.132.208
