Not bright enough. I want a 250w one

Yes that is more like it but they did not have any.

I have a pair of 100W LEDs here, just don't have the circuit to drive them.

If I were you, I'd be fr more concerned about dealing with the heat. Those
emitters will dissipate more than 50 Watts each.

**What a load of crap. They would have to be the most shitfully inefficient
fluoros I've ever seen. My bog-standard, 36 Watt Philips linear,
tri-phosphor tubes do 3100 Lumen. My more expensive quad phosphor tubes are
better still. Greenlife manage the same light output from an 85 Watt cfl.
Crap. The latest Philips cfls do 1550 Lumen from 24 Watts.

It's all very well to look for high power cfls, but try to find ones that
are actually reasonably efficient. That Chinese crap is simply not good
enough.

I have used T5 tubes, as well as 37w Quad and some 36w tri phosphors
(am replacing with quads as they die) at home and work
They give far more light than equivalent standard CFLs in my
experience, and there has been a drop in the power bill.

I think you would get as much or more light out of a pair of quad phos
37w tubes.

I would also be interested in how much that CFL thing weighs and how
hot it gets.
Some of that company's CFL's were advertised as Tri Phosphor BTW.


I wish that they hadn't raised electricity prices so aggressively,
locally it has led to a few people
installing wood heaters, which has resulted in smoke hanging in the
air at night - this was from just
2 of these things.

probably, depending on the specs (which I don't know) but if it is

100w device (compared to claims that it will give equivalent output to
a 100w incandescent) , you will need about 9a @ 12v

You would want to have the fan running too, and absolutely

excellent thermal bonding to the LED. 50w is a lot of power to
dissipate
particularly in such a small device.

You are probably right on the pollution (as in smoke and smell). When
it started this afternoon, I got on the roof and looked around to see
where it was coming from and found that all was coming from one metal
round stovepipe that looked rather old. When we went for a walk, I
was surprised at the area the smell covered, smell and smoke was
noticeable probably 1km away. (fairly still air) Closer to the source
it discoloured the sun light. A little goes a LONG way.

I had noticed this smoke in other parts of the city during the week
and wondered where it was coming from. After seeing an article on the
local news about record sales of wood stoves/heaters due to the
electricity prices, I now know. We are not in a country area, its a
suburban location.

As for electricity prices, you can thank privatisation for that.

You are - and apparently always will be - absolutely clueless on these

some reason.

I wonder where 'Dr Karl' got his info from, or whether he bothered to
verify it for himself? It's sounds highly exaggerated to me. How much
particulate escapes depends on so many factors...

Using wood for fuel releases the same amount of carbon had that same
piece of wood been left on the ground to rot... albeit it releases all
that carbon in a very short time when burnt.

I'll happily keep running my wood heater(s) and combustion stove until
I keel over and cark it. It's none of yours or anyone else's damned
business.

As for electricity prices, you can thank privatisation for that.

That's one way to put it. Have you not noticed that our entire
'government' was 'privatised' years ago?
