Thank's guys for responding, much appreciated!..........Ya I thought a little more light underneath wouldn't hurt!,now that I know it's a good idea I will certainly fill the voids between my plants with mini-spirals and of course maintain a comfortable distance between the lights and plants,even thou I held the mini- spirals in my hand for several minutes while plugged in and my hand felt warn even left the light on for several hours and touched the light still just warm.
