Just purchased the Firehouse Spark. Very well made and only 30 bucks on sale. The clear dome makes it quite visible at side angles compared to my Arc-II's. They are somewhat larger and come in white strobe effect only, but the case has an external power switch that's more user friendly than the Arc-II's. They also have a tie clip type fastener on the back but also come with velcro strips. Size might be an issue on the smaller multi rotors depending where it's mounted. Actually planning to use these on a couple of planes I fly. Probably try a range test between the two down the road but side by side the Spark looks brighter.
