DIY conversion of halogen/incandescent deck light to LED

[skyflyer]

So I guess it isn't a 21W equivalent, that was my assumption as it's a reversing light.

Got a link for it?

The lamps were similar to these, 7W not 20W as it happens http://www.ebay.co.uk/itm/2-x-7W-11...Bulb-EPS-UK-/291249131627?hash=item43cfcd106b

Yes I think we're getting muddled! The original halogen bulbs are 20W, which would seem to give about 200 lumens. The LED 7W seems to be about 300 lumens from what I can find online.
