Hi,

A friend on his narrow boat has installed a separate lighting circuit using the low energy 240 volt bulbs fed from an invertor on his 12 volt battery bank and he is convinced it is a far more cost effective solution than trying to replace his existing 12 volt bulbs with LED equivalents, he also feels he receives a far better and stronger light level.

Have any of you experts tried this is it more cost effective as the 240 Low Energy bulbs are next to nothing now, the 99p shop had 5 philips bulbs for 99p the other day.

That is thought provoking. I have to agree with better light and cost effective. It may be less efficient electrically depending on how good his inverter is.

In a MH though, none of these cheap 240V lamps fit our existing fittings ( well mostly true )

no difference in the bulbs......

it seems a 20w (equivelent) led will draw around 130 milliamps @ 12v
and a 100watt low energy bulb is rated at 130 milliamps draw @ 230v.

you do need to take into account the inefficiency of the invertor though...maybe 10% loss.....but obviously the light output is 5 X as much (eventually, when its warmed up)

then consider the cost.....5 X low energy for a quid .......... one led for around £8
