I'm exploring options for emergency lighting systems and would like to get more details on what you offer. Specifically, I'm interested in the various types available, their features, and any certifications they might hold. Could you also provide information on pricing, lead times, and bulk order discounts? Additionally, it would be helpful to know if you have recommendations based on specific application scenarios. Looking forward to hearing from you soon!
