Your source for beleiving MR16 will be "outlawed" within 5 years?

Really there is some crap talked about lighting by the half informed.

I guess you've come over from the uk.tech.digital-tv group? Andrew Gabriel
has been posting on uk.d-i-y for many years and has consistently shown
himself to be pretty clued up on lighting. Which is not to say that a
request for references is unreasonable, but the "half informed" slur is
... well, half informed :-)

I used to be indecisive but now I'm not so sure

Nope, been here a while, and sci.engr.lighting for a lot longer. Mebbe
its posting from google groups means am invsible.

Great respect for Andrew and his generally helpful responses known
also as a fellow poster to sci.engr.lighting for many years, sorry if
appeared to single him out for talking half informed crap on this
particular subject ,its really not personal but strongly disagree with
him on this point and interested as to where this is all originating.

Have come across this same nonsense recently both in the virtual and
real world, halogen lamps are inefficient crap thats going to be
illegal within 5 years, MR16 lamps wont be available anywhere but back
street `bulb dealers`.

Just to tidy up slightly, MR16 is a shape of lamp, its a 2" diameter
reflector lamp.

It can have all sorts of bases GU10 and GX5.3 for two and all sorts of
wattages and voltages for all sorts of applications, for reasons of
clarity will call the 230/240V MR16 a GU10 and 12V MR16 an LV lamp.

LV MR16 was introduced as display lamp for commercial premises
replacing PAR38`s and crown silvered lamps around the mid 1980`s.

GU10 was introduced for reasons probably more to do with lamp makers
margins than it being a good idea, 110V probably works marginally
better 230V has always been heavily compromised, lifetime , colour
temperature and beam control are crap.

For some reason contractors and developers think GU10 is easier and
cheaper to install than LV MR16 , perhaps ones who didn`t understand
Low Voltage first time around, yes have seen qualified electricians
hook up LV lamps to mains.

LV halogen has excellent colour rendering, excellent beam control and
very good efficiency for incandescent.

Fluoro retofit lamps for GU10 are universally RUBBISH, they are crap,
they do not work, they are a waste of money, hope made that clear
enough they are green wash of the very worst kind.
,
Half informed, the proponents of MR16 is soon to be illegal, always
seem to fail to suggest any realistic AVAILABLE alternative.

Mr Gabriel specifically because his advice is usually good, is liaible
to have his view that MR16s are about to become no longer available
given more weight.

But like others of this MR16s are a dissappearing breed persuasion ,
seems very light on alternatives.

Have suggested a couple in a previous topic , do realise there is a
difference between what is available to commercial users and what is
availble in small quantities to domestic and D.I.Y. users.

Scaremongering about lamps being outlawed without any evidence or
suggesting valid alternatives is not helpful to the debate.
