Voltage drop in garden lights

General Technical Stuff 1 Comment »

Hi,

We inherited a 12 volt transformer set up in our garden and I’ve recently
had it OK’d for use by a sparky so I’m looking to buy some spotlights – my
question is how do I know what size cable to order for our garden lights?

Thanking you

Downlights leaving burn marks on ceiling

Downlights, General Technical Stuff 2 Comments »

We have numerous halogen downlights in our rented home. They all have square discolouration in the gyproc around them very well demarcated. I think it is related to heat produced by the downlights affecting the gyproc and causing dust etc to attach to this area.

Our landlord is trying to suggest we have damaged the gyproc in some way. There are no other discoloured areas anywhere else on the ceilings.

Could heat from halogen downlights cause this problem?

Thanks

What is the true life of a CFL compact fluorescent

Energy Efficient Lighting, General Technical Stuff 1 Comment »

Hi There

I am the head of the body corporate of our building and currently using incandescent globes in our fittings in the common areas. I would like to use compact fluorescent globes CFL to try and save electricity but also save on our building maintenance costs.

We will get the same life that is quoted by the manufactures if we have the lights on for extended periods at a time?

Looking forward to your response.

Kind regards

How hot does a halogen globe actually burn?

General Technical Stuff, Halogen 1 Comment »

Hi,

We have just moved into a house with what seems like hundreds or MR16 lights (all put in around eight years ago), I will remove half of them (pitty the poor soul who’ll be patching the plaster on the ceiling) as these two rooms already have incandecent lighting, this should save power and heat.

The other half of the MR16 lighting is under a flat tine roof which was assembled TIN/SilverInsulation/Insulation Bats/MR16 Down lights, at points the Bats were touching the MR16 lights, I have replaced all MR16 globes with 20w ones I purchased from you and tried at best to remove the Bats from around the MR16 lights but being at flat tine roof at this point it is quite hard.

My question is this, how hot do the 20w globes get as I understand the 50w are in excess of 260c so I estimate the heat to be around 104c reducing the fire hazard considerably (I hope). Also, what is the power consumption of the transformers and do they represent a fire risk?

Regards,

Metal Halide Shop Lights

General Technical Stuff, Metal Halide 1 Comment »

Hello Lighting Pro

I’m renovating a pharmacy shop. Basically I’ve got normal halogen downlights lighting up both sides of the wall stock. I have 6 downlights on each side spanning ~9m each side but the lighting is still very dark.

I was recommended to get metal halide shoplighters.

Just want to know if that is suitable and whether 70W or 150W. Will 70W be too bright.

Many thanks
