The SOX-E 18W alongside a 7000K 13W preheat start PL CFL. That's a Bayco worklight from walmart with the tube guard removed.

With longer PL and LPS lamp, they would qualify as lightsabers

Interesting photo!! , a 13watt fluorescent that seems as bright as a LPS lamp, and this is why LED is taking over road lighting, as it seems white light at lower wattage can equal the high efficiency players in the lighting world?

Current: UK 230V, 50Hz
Power provider: e.on energy
Street lighting in our town: Philips UniStreet LED

I was just about to mention this. Despite putting out less lumens than the 18W SOX, the PL lamp probably does just as good as if not a better job of actually providing usable light. White light (which contains more blue) is better for dark adapted vision and studies have shown reactions to be quicker and safer under white light. I like SOX in large quantities but I find driving under orange light you don't feel you can "see" as clearly as under white light that is well distributed. I think SOX is best for motorway junctions or other interchanges like this but in areas where you're likely to have a lot of pedestrians I'd rather something else. Some people still cling to the errant belief that SOX spectrum is at the peak absorption of the eye but this is not the case for dark adapted eyes, and at that level SOX is actually quite inefficient.

Be careful running lamps on carpet, they can get rather hot

Well I think we're going to have to agree to disagree here, I much prefer driving under SOX light than white light. Sadly I don't get much of a chance these days

Now I want to convert my worklight to 18w SOX!

My very first word was LIGHT!

I've yet to get an 18W one, they're lovely little lamps

I'm also not sure about the effectiveness of bluer light. Looking at these graphs might convince you that sodium light is closer to the peak of our cones. (If you can see any hint of color, you're using photopic vision - your cones). Rods (scotopic vision) peak in the blue-green (at 507 nm) not the blue. However, research indicates that rods (and possibly circadian cells) AID our cones in very dim light. I believe this can be confirmed by looking at distant (dim) blinking blue LED security indicators in cars. The blinking LED light mysteriously disappears when centrally fixated while the deep blue color reappears by averted vision. Try it yourself.
