Posted on my club web forum by another member who is seriously impressed by these

They look like a steal at the price

Yes - but read some of the comments on build quality from people who've dismantled them. I'd still be tempted to give it a go though.

I'ts about 100ish lumen/watt like all the top end LED's at the moment.

The difference with this on is it has four physical dies in the package wired in parallel. You need to dump about 2.7A through it to get the full output.
