Replacement LED bulb for Lumotec 6V/2.4W halogen bicycle light?

[MGLloyd]

I recently purchased a Lumotec Oval Senso Plus halogen bicycle light to run off of my Dahon hub dynamo system. The hub dynamo puts out 6 volts at 2.4 watts. The light comes standard with a 6 volt/2.4 watt or 3 watt bulb.

I have been disappointed at the quality of the light output. Is anyone aware of a drop-in LED bulb replacement that might work? Thanks for any suggestions.

I believe it is the Philips HS3 427H bulb orginally, with a bayonet mount. More information is here:
