And you thought a 1000Lm replacement for a 9000Lm light would be a good
match?

You didn't read the original thread. I didn't /want/ a 500W equivalent,
something approximating to about 250W would have been fine as it only
illuminates a small area.

It was only a fiver delivered from China and I was curious to see if it
was any good. Nothing ventured, nothing gained.

Added to which the LED seems to be a 360deg version so it wastes 30% of
it's
light on the reflector of the lamp.

I ordered that one precisely because it uses the reflector in the same
way as the original halogen tube. The reflector is bright and clean,
and has dimples in it that scatter the light, which coming from LED, is
quite directional. I really doubt 30% is wasted.

I would say it's about equivalent to a 100W incandescent, which is what
some people suggested in the original thread. Having seen it working in
the dark last night, I think I'll leave it in as it's adequate. it's
just a big change from the f-off 500W it replaced. It goes on and off a
lot in the night so the energy saving will be worth it.

There's another light on the side of the house, I may try one of the
alternatives: the wedge-shaped one with LEDs on the front, like ebay
351337931867.

Again, this is just out of curiosity. I asked for recommendations for
replacement lamps and got none. Merely thought people would be
interested to hear about my experiences.

I missed your original post:-(

After a bit of searching I have found it. You said in that thread (after
buying the LED)

"I chose this one as it has LEDs all the way round unlike some of the
alternatives, so it actually uses the reflector in the fitting."

That is the wrong way to use linear LEDs. It's their directional ability
that allows them to be classed as equivalents to the lamps they are
replacing! Not using the reflector with all the 10W light only on one side
of your lamp would give a much brighter output.

All the LED flood lights I have fitted have nowhere near as much beam spread
as any halogen light but they are getting better.

If you do buy the other LED which does not use the reflector I would be most
interested in seeing how it compares with the first LED.

Cheers

I've ordered it. Note it claims to be 15W as opposed to 7W for the one
I reviewed.

This one:

http://www.ebay.co.uk/itm/261759028341

the J118 15W 48 LED one.

50k hour lifetime. H'm. Not sure I believe that

It's coming from China so will be a while. Will report back when I have
it in my hot sticky little hands.

cheers.

I bought the 30w LED floodlights Lidl had on offer a few months ago. They
appear to have only the one LED, but it plus the reflector gives an
extremely wide and even spread of light. If anything, better than the
halogen units they replace. But nothing like as much light. However, they
are bright enough for the task here.

When I see statements claiming LED gives about 10 times the light watt for
watt over halogen, I simply don't believe them. None of the ones I've
tried gets anywhere near that.

They have lots of LEDs.
The little module in the middle has a load of surface mount LEDs on it.
Probably 60+ for a 30W one.
