I have 2 of these floor lamps which give great light but unfortunately use 300W Halogen Double Ended Globes (eg see http://www.officeworks.com.au/retail/products/Furniture/Lighting/Globes/Halogen-Globes/PH300TH)- does anybody know of a low energy alternative globe? Otherwise I would have to buy a whole new lamp to accommodate a low energy globe.

MemberThose globes are likely to be relatively small, and a fluorescent with equivalent light output would be much larger. An LED light with similar output would need a large heatsink, or a fan to cool it.
I'd look at replacing the entire floor lamp. Waiting another 2 years until there are more options is another idea.

MemberFor uplight in my house, I have T5 fluorescent tubes mounted above the window pelmet. The pelmets were made with space underneath for curtain rails, and a 50mm deep tray above for lighting.
Wall sconce lights is another option, but I had lots of trouble finding some suitable fluorescent models. If you put a compact fluoro with ES or BC base into a sconce meant for incandescent bulbs, then the light source is in the wrong place and they throw a wonky light pattern on the wall.

Key MasterI have two uplighters at home, they were low cost ikea units with ES27 bulb bases, I currently run a 12 watt par38 LED bulb in one and the other has various bulbs, depending on what I'm testing at the time, but usually a LED bulb of some sort. The par38 lamps was an ebay unit from LED BULB Bizz ebay store, it is rated around 1000 lumens and uses cree LEDs, must come pretty close to it's ratings as it lights a room pretty well.
For pelmet lighting, the simplest solution is a strip of LEDs, either a premade strip that is just stuck in place, or for more light, get some 50 x 3mm aluminium strip and put a power LED every 6 to 12 inches and drive them from a suitable power supply. All of this stuff is readily available and pretty low cost nowadays, if anyone wants more info and sources, just email me at the ATA office, lance@ata.org.au

MemberI too have one of these uplights and wanted to retire it.
So far we've visited 3 light shops and found nothing that comes even close to providing the same level of lightThe idea of lighting behind pelmets looks like a good long-term solution, but doesn't solve my immediate problem.
Ikea with LEDs might be worth looking at though

MemberLance,
Your description of LEDs on an aluminium strip is what I am planning to do. The pelmet currently has 6 x 28W fluorescent tubes (it's a large room), giving illumination of about 40 lux. If you are watching television, and just need enough light to navigate around the room, then less light would be better. My current plan is to use one LED per 0.5 to 1 metre. Power would be 20 to 60W, probably using a dimming controller. I've got three Cree XR-E LEDs unused, so first step will be to see how it looks.I thought of using premade strip, but it's more expensive and the power will be higher than I want.
My other LED light idea is to take an existing 195mm diameter recessed ES fitting with frosted glass, and to replace the compact fluoro with an array of LEDs. Since the efficiency is about the same as the compact fluorescent, and the only gain is from better directional characteristics, this is low priority.

Key MasterGhostgum,
there are lots of pre-made LED strips out there, LED ribbon has 300 LEDs per 5 metre roll and draws 24 watts. You can cut it to any length, and it's pretty low cost. You can get it with various sized LEDs, and some strips have 600 LEDs per 5 metres, half of them cool white, half warm, so you can mix and match the colour temp. There's lots of options out there.Re the downlight, the simplest solution there is to just slot in a suitable LED bulb like the EvoLux from http://www.earthled.com, I'm testing a couple of those and so far they have been fine, and you can't hear the fan inside them from more than a metre away. You should also check out the Cree LR6 fitting (http://www.creelighting.com/LR6-230V.htm ), they are available here but they area bit scary in price, around $200...
