STRF4-3528-W3-12V-WP-T |
these have the 3528 smd led's with a lower lumen output 180 -200 /m
power draw is 4.8 w/m
efficiency is 0.024 to 0.026 watts / lumen
STRF5-5050-W3-12V-WP-T |
these have the 5050 smd led's with a higher lumen output 200-230 /m
power draw is 7.2 w/m
efficiency is 0.031 to 0.036 watts / lumen
it looks like the 3528 puts more energy into light and thereby less into heat
the biggest issue is regulated 12v supply over voltage may damage the unit
for switching a small latching push button would be easy (push once for on again for off)
for waterproofing circuits I use something called Dragon Skin FX pro 2 part silicone (generally used for casting makeup appliances) non-conductive and works great. Good for ip67 rating if you encapsulate your components and prep your surface
