Not 7 watts. 22 watts I installed 19 of these lights and was having issues with the transformer I size them according to the 7 watt rating per light the breaker is tripping. I did a test and found that the 19 lights were drawing a total of 35 amps at 12 volts. That is significantly higher than their rating.if you do the math you'll find out that is 3 times more perlite been rated.I did not test each light individually so there's a chance one or two or possibly three lights are drawing more power than they're supposed to but I find that unlikely at such a high number without them burning out.I ended up spending an additional $200 on a transformer that could supply the high enough wattage output to keep these lights lit.
