Thank you for posting. A lot of helpful info, never did I think about the wattage on the warmers having an affect on tarts. I'm just now trying to make them, I have a scentsy and one BHG i got from Walmart, both plug in the wall, I'm testing a paraffin pillar/gb 464 blend. The tarts have cured a week and smell strong, but tested in the BHG warmer, 15 watt bulb, and one square melt, the ht wasn't that great, so guess I'll try 2 squares and go from there, they smell so strong in the clamshell tho.
