My son once said He would never try drugs ....now He has hep c and will carry it for the rest of His life, I have become cynical I suppose, and for that I appologise, I did not intend for my post to "jump down" someones throat, after all it is hard to judge if someone is truthful or not on a forum, I just happen to care for my fellow man a bit more than most I suppose, if any offence was taken, then I appologise for that too, it was never intended ...
Manoftalent I have read previous threads where people do want to put themselves at risk so I understand your concern for people's safety and appreciate your concern.
I also understand a lot about drugs and hep c as I have worked in this field for 17 years. I wish you and your son all the best. People can live pretty normal lives these days with the various treatments on offer.
Patty thanks for your info, I now know what to ask for at the lighting shop!
Thanks everyone.
Cheers

I do not recommend downlights. I am an electronics engineer and was involved with the electronic transformer design of these units. The transformers are efficient but lamps and fittings get heated. Also require special handling of the globes. You cannot touch them with fingers while installing the globes.Quote:

Solid -state lighting is the future. SSL creates visible light with reduced heat generation or parasitic energy dissipation. In addition, its solid-state nature provides for greater resistance to shock, vibration, and wear, thereby increasing its lifespan significantly. Costs will reduce in future. LEDs have the potential to achieve 90%+ conversion efficiencies as a light source
Solid state lighting promises to create unprecedented changes in what we can do with light. Simultaneously, it will deliver on a promise of massive global energy savings and access to useful nighttime lighting that has not been conveniently available to nearly 2 billion people around the world.
Consider this: Halogen filament lamps used in headlights have already been replaced by LED's in LEXUS Automotive headlights. Downlights are hologen lamps
Lexus has unveiled the LS600h L ... It also has the first LED front headlights of any production vehicle.
So what you are saying is you did a shyte job?Quote:

Ignoring your attempted insult. Surprised you tried this crude reply-attack on this decent board.Quote:

I do not like the bulbs because they waste energy as heat. Besides down lights are not optimum light sources.
So how come you replied?Quote:
Ignoring your attempted insult
I amused myself anyway, which was my main object. It is funny: "I was involved in the design but they're no good". Classic!
You want to learn to lighten up a bit.
Anyway, to your other points, yes I'm sure LEDs are going to be the standard one day. A bit pricey at the moment though. It will be awhile before you see them in the average home I reckon. In the meantime, you can cut down energy comsumption by switching to different globes.
Learner what is the wattage of this unit?
100 WattsQuote:

cool looks good thx for the link will check it out
Have you got any links to pricing info?
Price is very high for the fluoro tubes. It is like the flash USB memory stick when first introduced in the market. We can expect the price to fall in few years.Quote:

That's what I thought but I couldn't find any prices on the LED lighting sites I checked.
I know that standard fluoro is the most economical as you say, but it's not exactly the most attractive. We've talked about dimming etc. of fluoro on other threads as a disadvantage. There are the fluoro replacement globes for standard halogen globes.
I think what people want at the moment is something that is as effective as what it is replacing, that uses less power, and isn't going to take them a number of years to realise the runnning cost saving over the cost of purchase.
You might say to wait until LED is cheaper, but as you say that could be a number of years away. When an LED lamp is around the same cost as a halogen, then I think all new houses will go that way, rather than halogen.
In the meantime, isn't it hard to recommend LED as a viable alternative?
