"I just want a simple "Is there and LED equivalent to a traditional 150W bulb?" (I'm using a compact florescent, but I still think of it as an old 150W when comparing.)"

Off the top of my head a plug in replacement would be around 12 to 15 watts as a LED and I can't call to mind one either at http://www.ledcentre.uk.com/ or http://www.lightbulbs-direct.com/ (my favourite source for daylight balanced fluorescent lighting) The closest would probably be on Ebay. For example http://www.ebay.co.uk/itm/280687560279?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 The 'corncob' design isn't the most aesthetic but it's an interesting compromise.
