Hey there,
Just wanting to know what uses less power to run? Is it 12v 50w downlight or a 240v 50w downlight?

Osram IRC Light and Heat Output

Could you tell me if the Osram Decostar IRC energy saver Halogens are suitable for placing in ceiling spots. Thats assuming the heat behind
may be too high!? The spots are currently using the standard Decostar, so I assume the heat from those would be just as high from behind!!

Looking for an energy efficient lights to replace downlights

I am looking for an energy efficient lights to replace my current downlights - the cutout is 80 mm and I found a fitting through Cosmoluce model GE5009 WHT which seems to suit. I am interested in moving to the GU10 CFL globes you speak of on your website. Do you have anything similar available?

Lamp holders would be suitable as a push bike light

I rang today as I’m interested in the 6V MR11 (35mm) Halogen Dichroic $9.95 MR11, 35 mm diameter reflector. Available in 5 watt (30 degree beam), 10 watt (10 degree beam), and 20 watt (30 degree beam), with glass cover and G4 base. Used by a lot of bike enthousiasts as head lamp globes.

I would require it as a push bike light and was wondering if you feel it would handle the bumps and vibrations in such use. Also, would you be able to sell or suggest what lamp holders would be suitable and how much?

I would be interested in one of each globe, holders and postage to Melbourne.

Dear Daniel,

Downlights with or without transformers. Which one is safer? Which one is less expensive to run?

Would appreciate your thoughts

Kind regards

how do I change a halogen bulb

Halogen 1 Comment »

Hi there,

It is the first time I have come across a 78mm linear halogen tube.

I am basically not sure what is the correct way of installing and removing them from the fitting. I had to replace one and I had troubles just removing it. I ended up literally destroying one side in order to get it out. I bought a replacement (and just realised that I could’ve got it much cheaper on your site - will know for next time now) and I just cannot put it back.

The fitting’s sides are slightly retractable but I still can’t put the tube in.I am afraid forcing it too much not to break it. Can you please let me know what is the correct way of installing and removing these tubes.

Any advice would be very welcome.

Until I hear from you, we’ll just be in the dark.

Regards Damir

Dangerous Heat Caused by Halogen Downlights

Hi Daniel,

I have halogen downlights downstairs in my 2 storey home. I can feel “hotspots” in my timber floor upstairs directly above the halogen down light and am concerned about a fire hazard.

It would be hard to put in one of your heat guards without cutting large holes in my ceiling. There is about 15 cm between the ceiling and the floor above.

Would I be better off with a low voltage aluminium reflector bulb.

What can you recommend?

Great site BTW.

Cheers.

Why do we use so many transformers in our roof

Halogen 1 Comment »

Hi Daniel

I was told that there are transformers that can run more than one 12 volt quartz halogen lamp connected to them. If so can you please advise why do we normally use one transformer per downlight. I was considering installing 3 down lights in the kitchen area of my home to run off one transformer and was wondering the pros and cons of using one 12 volt low voltage transformer would be.

Thanks

Bill
