TRAVEL INFORMATION

ALL 2 CELL POWER BANKS ARE 26 WATT HOURS (WH)

HIGH CAPACITY 4 CELL (BLUE LABEL) ARE 52

HIGH DISCHARGE 4 CELL (SAR, RED LABEL) ARE 38.5

POWER BANKS ARE ELECTRONIC DEVICES WHICH CONTAIN LITHIUM BATTERIES, THEY ARE NOT JUST "BATTERIES"

I am offering this information to help travellers, but obviously not responsible for any travel restrictions that may be in force ant any particular country.

As an aside, the WH rating for the size and weight of the power bank is a good indication of the quality of the batteries it contains. Some lamp manufacturers my be reluctant to state the WH for this reason.
Ultra high discharge, that is a safe 20 amps per cell discharge, results in a lower capacity. However to the best of my knowledge there is only my SAR lamp on the market that needs this specification of battery.

Due to holidays and other commitments I am unable to take any new orders until further notice.

Please pass this around.

If someone on here has sent an X2000 in, can you please let me know who you are etc, no advice note or anything. Cant see anything wrong with it except a bit of moisture got in somehow.

I am now fitting better cable glands rated at IP68 and with cable protection, so it will get upgraded anyway.

Also, back orders etc filled and back to normal with most lamps in stock.

2 cell power banks.

There has been a design change to move to all aluminium cases, as shown below.



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

These are inherently stronger than the plastic ones, price is unchanged.

Other changes
The all popular X2000 now has daylight matched colour temperature XP-L emitters which also give more output.

The new cable gland is universal to lamps and power packs, as it is a much improved component and also is IP68 rated.

Some issues with other power banks.

Issues have come to light regarding failure of inner strands on power banks of the earlier type with metal cable glands.

Batteries affected have soft rubber cable (not PVC) and metal gland.

The issue arises where the cable is under some tension and is a product of the fitment to the helmet. Many have now been in use for several years without issue.
I am accepting returns on failed items and turning them around as soon as possible with upgraded gland.

Very tidy. Any thoughts on an upgraded battery mount?

If you mean the shockcord I doubt this will be changed as its effective and adds no bulk in the way that some kind of fancy mount would do.
A bit funny, another 'manufacturer' that I will not name does not supply any kind of mounting and 2 people asked me to mount their batteries for them in this way.

The technology is very much in a state of flux at the moment with new battery technology being developed, any kind of investment in current state of play would be a folly.
