Other than the price, the main reason I am looking for an alternative to AA is to gain more "set time" I am positioning 8 to 12 leds in a confined space that also will have optics with holders on them. I am really within 1mm at best between spacing them. By using a cement that will take time to set, will allow me to precicely place them so that when the optics holder are attached, they just barely touch each other.AA sets way too fast and by the time I have the 8th one in place, the first ones are already dry, and cannot be re-positioned.Here's my sequence of production:I apply the adhesive on the leds, I roughly position the leds on the heat sink within about 2mm from where I really want them, I attach the optic holder to them without the optics, I slide them around untill they are in place, wait for the adhesive to dry, take out the holders, solder them, cement the holders on the leds, put the optics in. Any improvement to my method is appreciated. Thanks
