Here is a little review I posted elsewhere for your reading pleasure, involving the exact lights the OP asked about. One thing I will say is that since I bought these, an alternative low-price driving light showed up that I would've gone for instead. They're listed as OSRAM, but I don't know if they actually are or not, but they look very similar to these, but are a tighter beam and 30w. I'll search around for a link and post up.
EDIT: here they are...I may actually order up a pair of these this week, so if that happens I'll post an update comparing the two.

cliff notes: I bought some cheap-ass LEDs, and they aren't as awful as you might think.

I know there's a reasonable likelihood that I'll get picked on for going cheap, but the thread does mention 'reasonable price' and I have had some success with this setup. It's important to note that I don't use aux lighting for conspicuity, so there's no info here on dimmers, etc. Here's a review...
Ok, so I am well aware that in the world of LED lighting, it is in fact fairly reliable that you get what you pay for. I say it like that because it is my experience that this phrase is almost always secret code for "I'm too lazy or ambivalent to actually learn anything about what I'm buying, so I'll just spend a lot and hope for the best." But, with so many very inexpensive LED driving light options, I decided to try a cheapo setup and see how it worked out. I figured if it sucked, I'd at least learn something, and I'd just scrap it and start over with relatively little money lost. Turns out, it's not so awful.
I bought lights off of Amazon that are branded 'Nilight' but these are the same as many other generic Chinese eBay specials. I like the service and shipping speed with Amazon, so I went there (I'll provide links and a pic of the bike below). I bought a pair of the 18w lights (black, 6 diodes each) and a pair of 30W 6 element lights. these were $40, but you get a pair of them, and I only needed one. They might be available individually, but I didn't see the option. Here are the links...

Performance: Just so you all know, I'm not a skimper when it comes to lights. I give you my word that if this had sucked the test ride would have been the last ride for the lights. Interestingly, it wasn't terrible.
Build quality: I don't have enough miles on them (1k) to speak to longevity, but apart from that unknown, the build quality is beyond reproach. I have a pair of Hella halogen lights that are left from my Sprint, and these make the Hellas look like Wally World rejects. Really, they're that solid. No issues in any way.
Light: All of the LEDs here are sold as 'spot' lights, but even though there is a clear concentration indicating an effort at a tight-ish beam, they're still pretty floody. Not enough to hinder vision at distance, but enough that you have a feeling that the entire scene in front of you is lit, more so that you would with very concentrated, tight beam spot lights. This is especially true of the two 18w lights. The 30w light is predictably brighter, but it's also a bit more successful in the 'spot' department. For the Tenere, this is a good thing, since the hard horizontal cutoff on the headlight makes nighttime corning terrifying. If you're a Tenere pilot, this setup effectively solves this problem.
With this combination there is a definite improvement down-range, but not a super big one. This is where the disparity between these lights and high dollar options is most obvious. That said, the OEM headlight on hi beam with OSRAM Nightbreakers is a fairly stout headlight, so for $40 worth of light to outreach that is an accomplishment, however small the improvement. Interestingly, this slight down range improvement is seen at a very wide pattern. I would have thought that the failure to keep a super tight beam would mean a lot of loss of brightness at distance, but this isn't really the case. This is why you get that feeling I mentioned earlier of the whole scene being lit. I haven't tested this last point, but I believe that the center light is quite a bit more effective than the side, smaller ones. I can't speak to how just a pair of the 18w lights would fare. i might try covering each to try them individually and report back if anyone cares, but so far I've only seen them individually when I was aiming them.
Verdict: If by 'alternative' you mean 'just as good as the expensive ones' then this experiment is a failure.If, however, you would like extra light at night, but can't afford the high dollar stuff, or maybe just can't justify the cost, I believe that these lights are viable. I'm pretty picky when it comes to light; I pretty much want daylight recreation capability on my bikes, and to be clear this setup does fall well short of that, especially down range. But, I will say that I am satisfied with it to the extent that I will be back-burnering further lighting upgrades until this coming winter when I will be milling around the garage looking for something to get into.
When I installed these lights, I was fully prepared to be disappointed, immediately return to the garage, and blast off a bunch of money on good lights. But, that didn't happen. For a total investment of $60 including a spare 30W light, I would call this a win.
I hope this helps somebody. Post up if you have any questions about this setup.
