Patlite preassembled stack lights are available in 25-, 30-, 40- and 70-mm sizes. They offer high-intensity LED illumination and prism-cut lens design for enhanced visibility from any direction and can be purchased in one- to five-tier LED module assemblies (depending on the series). Suitable for tight spaces, the 25-mm ME/MES series of rust-free aluminum body signal towers is designed to be direct-mounted. With an ABS resin main body, the 30-mm MP/MPS series offers impact and heat resistance. The 40-mm LCE series features low maintenance and energy efficiency using LED technology. The 70-mm LS7 series features a smooth body surface that reduces adhesion of water and dust.
