coralife replacement led's

Unfortunately I had one of my 4 led's on my 48" coralife aqualight burn out. I found two places on the net that have them but they are both out of stock.

The two places that have the part are:

and

If anyone might know of a place that does have this replacement LED for Coralife Lunar Aqualight I would be grateful if you can pass it along.

Thanks
