Barry,
What sort of budget are you thinking about?
That will more or less decide what to go for.
I was in Tom Snowdons shop in Belfast at the weekend and he has a few of the Metalsub umbilicals in stock in both HID and 50watt, I have a 50 watt that is currently in need of repair but I would strongly recommend them for being 'solid' and the fact it has a dimmer adjustable head.
A very good torch I have seen a bit lately is the Greenforce umbilical and they have a huge selection in both price and types look at
http://www.lumbbros.com/There is also a basic 50 watt rugged enough umbilical for about 140 stg from
will post the link as soon as I can find it??
Talk to you soon.
