Glowing Eyes - Max Power 3W Special Effects Glasses mechanical wings This is the version IHigh powered custom special effects accessory. These run on most standard USB 5v power banks (not included). Includes inline on off switch and standard USB connector. At 3 watts per side (6 watts total) these glasses are incredibly bright. Makes for a really cool effect in the darkness, they practically light up a room. CNC machined custom made aluminum heat sinks dissipate the heat efficiently but glasses will get warm after a few minutes.
