What type of lighting is safest for a high-heat application?

Trying to install accent lighting under a fireplace mantle, which obviously gets hot when there’s a fire. Halogen bulbs are a no-no – killed the bulbs after 2 hours the first time the fireplace was on. Will LED bulbs be safe in this application? If so, should I purchase a pre-integrated puck, or a fixture for MR16 or Gu10 lights? And which of those two options would be safer. MR16 means the transformer would be elsewhere, but it’d end up inside the wall or directly behind the plasma TV, so I’m not sure that’s any better – Gu10s would have the transformer right at the light, but can they handle the light?

Has anyone tried LED Lightbulbs?

I have several fixtures that use the GU-10 bulbs (like in this picture http://www.febri.pl/img/GU10-50.jpg ). As I understand it, LEDs are very ‘directional’ and not especially good for regular fixtures, but what about in ones that are meant to be directional? In any case, if anyone has an opinion on these, I’d appreciate it.

50W GU10 Halogen Alternatives?

I have a basement full of 50W Halogen Recessed lights running on 120V through several dimmers (controlled in sections). Only problem is that they run incredibly hot, while the rest of the house is nice and cool the basement is running like a sauna. I’m looking for alternatives and so far I haven’t found anything that would really solve the issue. I really don’t want to rip up all the lights to replace them with something else. I’ve looked into GU10 versions of LED (3-6W, expensive, tall, not dimmable), CFL (~11W, tall, not dimmable) and even Xenon Filled bulbs that promise to run cooler but I haven’t found any real data supporting it. I’d like to keep my dimmers if possible but I’m open to other suggestions. Even though I found dimmable versions of LED and CFLs, most of them are too large to fit in the standard housing (Catalina Lighting Recessed Housing) or only are available in 240V versions.

We have a wide choice of GU10 LED Bulbs to replace your halogens.

Can I use different power bulbs in the same bank of downlighters?

I have a set of 5 downlighters in my living room. I want to change some of the bulbs to low energy led bulbs, but keep three of them as standard GU10′s Can I do this safely without the risk of overloading any of the bulbs in the circuit?

How effective are LED Halogen replacement lamps? Also, how good are the coloured versions?

I have over 60 230v 50W halogen lamps spread throughout my house and a huge electric bill to go with it. So, I have been looking at ways I can economise a little by reducing the power.

I have seen LED lamps that last 25 time longer and use about 1/20th of then power of a conventional 50W halogen lamp.

How good are these alternatives? Is it a cold light? Do they not offer much brightness?

Also, as I use lighting to create effects in the house, I was thinking about installing just a couple of the colour changing GU10 LED lights within each circuit of 8 to give effect. How good are these?

I would welcome feedback from anybody that has used these before.

Thanks

Are gu10 48 led bulbs (daywhite) brighter than at least a 35w halogen gu10 bulbs? ?

I just ordered these and i am scared i will waste my money and the bulbs will not be bright. Are there any recommendations for replacement of gu10 bulbs?
