I was simply trying to help. Do what you want with it.
When it comes to voltage ratings, the key isn’t in the size of the traces (as is the case with amperage) it’s in the spacing of the traces to avoid arcing. I personally wouldn’t switch mains voltage with this thing as it is simply not designed for that and very likely would not meet electrical codes in most parts of the world. Usually when you have a device designed to switch mains voltage, the high voltage (120 or 220v) portion of the circuit is fully separated from the low voltage part by a significant amount of space. That is not the case here. With that being said, if you choose to do so, that is your decision, but you can’t expect Sparkfun to rate a product based on extreme edge cases that may be possible under the right circumstances, but could be dangerous in others.
It is more than likely a matter of heat dissipation, the capacity of the traces on the board, or even the rating of the screw terminals. Just because the relay itself is rated at a certain level, doesn’t mean this particular implementation can dissipate all that heat or move that much current through the traces on the board and screw terminals.

Anybody else find that you can only use this for short periods of time before it stops turning on for about 10 minutes. I often use mine for 15-20 seconds at a time, 3 or 4 times and then it will completely stop working. If I wait about 5-10 minutes I will hear a barely audible click and then it will work again for another short period and then stop again. It never stops mid stream, only when you turn it off and back on again.

Any chance of getting these in the style that lets you wear eyglasses under them? I use the slightly adjustable eyeglass compatible style safety goggles at work every day and would love to have them with the logo.

Why is the brightness on these listed as 4,000 mcd, when the brightness on the 25 pack and singles, which link to the same datasheet, listed as 10,000? Are these 10,000 mcd or 4,000?
No public wish lists :(
