if you need to know anything else do not hesitate to contact me.

I now understand where the figures come from now but may I ask the relevance of Halogen light output labelling on HiD lights? When HiD was new I can see that the information may have been useful in assisting buyers making informed choices but when it is the actual name of the light it is at best confusing if not misleading.

Some marketing bod may think it gives GF lights the edge to quote bigger headline figures than the competition but then why stop there? Why not quote 'glow worms'? The light industry already has standard figures which could be quoted: candles, kelvin and lumen as well as the figure directly relevant to the technology (i.e "18W HiD" for an 18W HiD like other vendors do).

This marketing approach could actually be counter-productive as divers may have their expectations set in the wrong place. This has certainly been my own experience when GF owners have declared their lights to be 50W HiDs, 100W HiDs and 250W HiDs before jumping in. If I had translated "100W HiD" to mean "similar to a 100W Halogen" then maybe I would have known what to expect, but when someone says that and I am holding a 21W HiD I am expecting something nearly 5 times brighter not significantly less effective.

Many UK divers use their lights just to illuminate holes and chase lobsters around wrecks and the GFs are plenty good enough for that application, as are most of the lights on the market starting around the £50 price point. I rely on my primary lights for much more than that and therefore have different expectations of light performance. Maintaining team contact in low visibility (especially whilst scootering) is central to my diving. Not everyone has that requirement.
