A good replacement for those Halogens
on 22 October 2011
This is a good replacement bulb, almost a perfect replacement for 50W halogens.
We have a number of dark rooms lit by set of 4x50W halogen lights on dimmer switches. The 7W Auraglow non-dimmable came out this year, and after putting a couple in the kitchen (no dimmer switch) we bought a few of these dimmable versions. Putting them side by side vs the old halogen bulbs showed up a few points.
These bulbs really are quite bright, and are (at long last) a true replacement for 50W. The manufacturers have done quite a good job in making them 'warm', and only in the centre of the spot is there a blue tinge. This bit is brighter than the equivalent halogen, so if you don't mind the blue it's actually a bit better - great for reading.
The light is more focussed, which does mean that one bulb will seem more harsh if aimed closely at a wall. Not really a problem with bigger walls, but noticeable with some colours and wallpapers.
We have MK dimmers, which are rated down to about 40-50W. This means 4 of these bulbs will cause the lights to flicker. Leaving in one halogen in a group of 4 will solve this problem. Of course, when dimmed, the halogen bulb is very low, with the 3 other Auraglows brighter. If you really need very low light, you'll have to buy a zero-load dimmer.
Currently these bulbs are still quite expensive - whether they will ever reach 35000 hours is rather hard to gauge (it's about 4 years continuous operation or about 20 years for normal use). We have found a good proportion of our electricity bill is from lighting, so these will probably repay over a few years.
With any luck they'll make some '10W' bulbs, so we can upgrade our lights to super bright. I'm sure this would be a good marketing ploy, actually...
