Reliable, high-intensity incandescent for sign, showcase, and appliance lighting—delivers bright, warm light with simple installation. These traditional bulbs are being phased out in favor of LED alternatives that offer 15,000–25,000+ hour life, significantly lower energy use, cooler operation, and similar brightness (e.g., 5–6W LED S11 equivalents).
