MB SUB LED Cave and Photon
Michael from MB Sub in Germany contacted me and asked if id be interested in testing out the MB Sub LED Cave umbilical torch and Photon LED Hand held. This tied up neatly with a weeks diving planned for the Orkneys and soon I was unwrapping my temporary new toy.
Before I start a little personal torch history is offered for perspective;
UK DR40 Hand Held (Sold)
Birchly Products 50W Halogen Hand held (Flooded and died)
Custom Divers 50W halogen Umbilical (Flooded and died several times)
Halcyon 10W HID Protius 3 Lead Acid Umbilical (I still own this torch no problems so far original bulb and 1 new battery)
Salvo 21W HID 9ah I still own this torch 1 new bulb in three years, original battery minor connection block and wiring issues 98% reliable)
Solus 1000W LED : On test only felt it was a little big but it’s a great torch
Solus 1250 LED Had it on test, Loved it, so I bought one
MB SUB LED CAVE FACTS AND FIGURES
The 1.64kg MB Sub LED Cave offers a 200m rated compact 9.6 AH battery pack and a single 1000 Lumen Osram Ostar LED. The head design is a fixed beam compact unit with a choice of Goodmans handle or hand held function. Canister is sealed for life Anodised Aluminium. No moving switches pierce the casing of the head or the battery pack with on off operation by magnetic proximity switching. The Battery pack is a LiMn, no memory, no natural discharge item with six hours burn time on max power and a further three hours on emergency power. The lamp has a high 1000lumen and low 600 lumen power setting accessed via a two position magnetic switch.
Switch operation is via a detachable ring. If the unit is used with a Goodmans handle the switch magnet is built in. If not you use this ring.
The small ball bearing seen to the left of the magnet (in the blue plastic casing), is the locator for the three switch positions. Off, Low Power and Full Power.
Charging of both the LED Cave canister and for the Photon Hand Held is via an internal jack plug protected by two 0 rings
The basic unit costs 759euro which comes with a travel charger and webbing loop mounting system. The following are offered as extras.
Goodmans Handle 67.00 Euro
Tank Holder clamp 59.00 Euro
Clip 48.00 Euro
There is also an option to buy the canister unit and the Photon hand held unit together and share a single lamp head. This option comes in at 899 Euro
Note: Piston clip is my own
Every item exudes the quality you would expect from a German manufacturer. A two year warrantee is standard and there is a three year extended warrantee as an optional extra.
The Charger was sent to me with out a power cord, but fortunately it took a standard two pin cable found on most electrical equipment these days, which allowed me to overcome this minor issue easily. Handy for travel, as I only need one plug and cable for multiple chargers.
I was swapping the torch over with Howard so I could shoot video and get his input as well. As a result I left it in the webbing mount mode and just cam banded it on to my 02 tank. The tank clamp is not cheep but for convenience I think id invest in one.
I mounted the canister on the 02 tank of my KISS using the cam band that supports the tank.
Having the control switch on the torch head made
this configuration easy to manage. The Goodmans handle has the same location ball and magnet operated switch. I found the switch operation easy once I was used to it and it could be done one handed as long as you got the handle on the right way round.
If the Goodmas handle was put on back to front, it wouldn’t turn the torch on. This minor inconvenience turned out to be a nice feature for transport. By turning the handle around there was no chance of accidental operation and subsequent heat damage. Under water it just meant unclipping the head and re clipping it the right way around.
I was initially concerned that the torch head and Goodman’s handle could become separated easily. In doing so the torch would turn off. I could imagine a scenario where a dangling torch gets caught and the Goodmans handle is ripped off and lost. In such an event you would lose the light source. I could see me cave diving with a spare on/off switch in my pocket. If you get the Goodmans handle a spare on off switch will come with the torch. This said I must stress it takes a considerable amount of force to separate the handle from the head and then only if the movement is in a specific direction.
