Are Wall Lights Dimmable?

Wall Lights 2 Comments »

I have recently had two dimmer switches installed on my mains lighting in the bedroom with a view to fitting two wall lights that can be dimmed. How can I tell which wall lights are suitable for dimming by this method…is it as simple as if it\’s halogen it can be dimmed? None of the wall lights I have seen listed mention that they can be dimmed unless they have a built in transformer…please can you help?

Energy Saving Alternative to Halogen Downlights

Energy Efficient Lighting 1 Comment »

Good morning,
My inquiry is in regard to replacing my 40 halogen downlights with energy saving ones.

My question I guess is what do you recommend, as I require lighting that is very similar to the 50 watt halogens.

Do you have lights that do not heat up like the halogens, if I am replacing them, safety is a big issue, as I worry about halogens and the heat they generate. Hopefully you can guide in the right direction.

Cheers,
Pete

Osram IRC Light and Heat Output

Halogen 1 Comment »

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!!

CFL got wet so Can I let them dry out

General Technical Stuff 1 Comment »

I purchased a couple of boxes of cfs to do the house, however when it rained and the globes were on the floor in the garage they all got wet. Can I let them dry out or? Also will the new CFs take longer and more detrimental to the enviroment when put in the rubbish.

Remove the flicker from these CF lamps

Fluorescent 1 Comment »

I have found a problem with the CF lamps and the digital scanning back I am using so I thought to ask your advice first.

The CF lights are producing a repeated (raster) pattern of very pale thin lines parallel to the scan direction (I only noticed them when processing delicate artwork like drawings – they’re there but not so noticeable with high contrast paintings).

I did some searching on the web and it seems that there is an interaction between the high frequency of the CF and the digital scanning back. So I was wondering if you know of any way (electronically, etc.) to remove the flicker from these CF lamps? Is there a special power supply one can use?
