RE: Bulb Temperature

["Young, Jeff" <Jeff.Young@xxxxxxxx>]

I'm freaking that all those (x48) 20w bulbs are going to create too much
heat and melt my plastic roof.

http://www.tlc-direct.co.uk/Products/LAM47.html

TLC are happy are to swap all my 20w bulbs for 10w but do you think they
will actually run at a lower temperature ? Or am I better off using 20w and
diming them by 40%-50% ?

Thanks in advance .....

My personal 'favourite' for gluing anything is Gripfill ... they do a
non-solvent based one too (incase any of the solvents may cause reaction ..
but I doubt it would do...

I would imagine the void space you have is plenty to keep it all
cool-enough
.. especially as the lights wont be on full brightness all the time ...

I imagine they will spend most of their time in a dimmed
state.  I may also
swap all my bulbs for 10watt.

I've had one on test for a few months.  I've got to be
careful with the
damp-proof membrane, so I've checked that the lights don't
melt it.  I've
got about a 50->60 mm void to mount the lights in and I also
plan to fix
some sort of ceramic tile behind each light to spread the
heat out a bit.
I'm trying to decide what I can use to 'glue' the tiles to
the membrane.  I
don't want to use something that may damage/react with the
membrane over
time and won't mind getting warm.  How about 100% silicon
sealant ?

Hi Jeff,

Wow .. that's plenty of light !!

I used the 10watt bulbs and my 14'x12' bedroom has 8 lights
on the ceiling
and 2x 20watt above the bed ... with them all turned on its
really nice and
bright !!

Have you 'tested' any of the lights (you know, 'just to make
sure they work'
before fitting them ) ? to see the amount of light they
throw out ? they get
HOT aswell

I'm using 4 x 250w transformers to cover 4 x
12 x 20w bulbs.
I'm putting in
so many because SWMBO wanted a nice stary
sky effect.  I
think it's going to
be more like Close Encounters with 36 lights
in the main
room ( plus another
12 in the next room ).

Control will be via my x10 remote or wall
switches.  Plan to
use Homeseer in
the future.  I'm installing an x10 motion
sensor to do the
if-no-movement-after-30-mins switch off
lights etc.

Jeff,

Those are the lights I've used in my bedroom
ceiling !!

I've used 1x250watt transformer for the main
lights and 1x
per reading light
(two lights above the bed with a switch
either side ...)

Just out of curiosity, are you using one
transformer per
light / per 'bank'
of lights  ?? hows it setup ? HV / comfort /
etc ??

Whats the story behind these 'ere vaults
then ???

Thanks,
Jonathan.
