I'm happy to say that the gamble paid off: these MR11 bulbs fit in this model flood light even though the bulbs aren't the same shape and they work great!
In fact, they're brighter and don't put off any heat. I've replaced 4 of my 20W with these and now I'm saving just over 75W of power PLUS I'm getting better light output on the whole line (I have a long run of low voltage lighting).
So if you're wondering if you can use these in other Malibu lights with the bi-pin style bulbs, I'd say chances are high they'll fit. I can tell you for certain, they fit the model number above.
Some advantages of LEDs:
1) Significantly less power consumption for the same light.
2) No heat.
3) Lasts longer (yeah the bulb costs more than the 7 dollar halogen bulb from Home Depot, but it will last a hell of a lot longer).
4) If you have long runs of low voltage lighting you can't usually go over a max of 300 watts totalwith LEDs, you can put many more lights on a single transformer.
I think there are some environmental savings as well but you get the point. Highly recommendedin fact I'm buying more to replace all the 20W's in my front yard. :-)
I bought MR16 versions of these also and reviewed them also if you want to verify model number compatibility on those.

I'm very pleased with this bulb in a nano aquarium setup. It's got plenty of output and the dispersion characteristics are awesome. The bulb isn't waterproof so I sprayed it with an automotive clear coat. Problem solved. The price and Amazon shipping just sweetens the pot on this bulb.Best Deals for Ledwholesalers Brightest MR11 12V 10 SMD LED Bulb Wide Angle
I've tried a number of MR11 and MR16 LED lights, and this was definitely the best of the MR11s that I've tried, and probably better than most if not all of the MR16s that I've tried. The light really is "warm white": it doesn't look out of place along side a halogen bulb. It also manages to be both very bright and wide-angle. Most of the LED MR11s and MR16s that I've tried in the past either had a very narrow beam (even when they claimed to be flood lights, not spot lights) or were very dim. This light is really bright, and the width of the beam is comparable to a halogen MR11 flood.The only possible downside to this light I can think of is that it uses an array of LEDs, and if placed very close to a surface (eg: if it's mounted on a wall, the wall right next to it) you may be able to see individual points of light on the surface, which sort of destroys the illusion that you're dealing with a single "bulb". Well, another downside is that I doubt that it is dimmable the way a halogen is (only because dimmable LED lights are almost impossible to find), but I don't have a need for dimming in my application, so that hasn't been an issue for me.
Honest reviews on Ledwholesalers Brightest MR11 12V 10 SMD LED Bulb Wide Angle
I compared the "white" version of this bulb to a 6 watt Ecosmart LED bulb from Home Depot and a 35W halogen from IKEA. The comparison pictures can be seen in the gallery. The first thing I noticed is how very blue it is. I was trying to order the "warm white" version which is quoted at 3200K in the product page's description, but I must have accidentally ordered the "white" version which is quoted at 6000K (somewhat colder than daylight). [Edit: The reason the right bulb wasn't ordered seems to be that it doesn't matter if you click on "warm white" if you originally clicked on the "white" version's page. You have to actually go to the other version's page.] It does look to be around the stated color temperature. I would not recommend this bulb for someone trying to light a room with anything like the type of traditional warm-looking light that's characteristic of incandescent or halogen bulbs. It may be suited to lighting an aquarium, or where light output is a priority over color temperature (like a bicycle headlight).It is also quite a bit dimmer than both of the other bulbs. It's quoted at 160 lumen (20 more than the "warm white"), and that does seem pretty close to what I see. It looks to be around half as bright as the Ecosmart which is quoted at 295 lumen, and less than 1/3 as bright as the IKEA 35w which doesn't have a quoted brightness, but likely over 1000 lumen. If I had to guess, I'd say this bulb is probably around half as bright as a 20w halogen. The light output also seems less concentrated in the middle and is more evenly distributed than the other two bulbs. The beam pattern seems in line with the quoted (very wide) 140 degree viewing angle, with a sharp cutoff at the edges unlike the other bulbs. Like the Ecosmart and most other LED bulbs, there is no light coming out of the "back" of the bulb as you would see on a normal halogen MR16. So there is no slight diffused lighting on the ceiling above the track lighting that the bulbs are in, which is a downside in my opinion.
The bulb is also about half the size of the other bulbs, which was pretty surprising to me since I didn't look at the product dimensions before I bought it. This is probably a big plus for those trying to fit the bulb in a small space.
The last thing I noticed is that this bulb runs MUCH cooler than the IKEA halogen, and even somewhat cooler then the Ecosmart LED. After only a minute or two the halogen is way too hot to get near, but this bulb is only slightly warm.

If you have a a fluvel edge aquarium these are the perfect replacement lights --i will need to get more lighting but these offer ample lighting. I am going to put a couple coats of clear coat on them to water proof them.
