Nisko Lumilux Fluorescent Tube Bulbs Guide — 2026 | ramo.co.il

T5 and T8 are the two most common fluorescent tube types — the number indicates the tube diameter in 1/8-inch units (T5 = 5/8", T8 = 1"). T5 is slimmer, more energy-efficient, and fits modern fixtures. T8 is wider, most common in older fixtures and industrial lighting.

For wattage: T8 18W suits small rooms and corridors (600mm length), T8 36W suits larger rooms (1200mm), and T8 58W handles large rooms and warehouses (1500mm). T5 8W and 14W are ideal for compact fixtures like kitchen cabinets and shelf lighting.

Light colour affects comfort: cool white (6500K) is ideal for offices, warehouses, and work areas. Neutral white (4000K) is pleasant for kitchens, corridors, and living areas. Nisko Lumilux tubes feature tri-phosphor coating for consistent, high-quality light throughout their lifespan.

By location: Office or warehouse — T8 36W or 58W cool white (6500K) for focused, productive lighting. Kitchen or bathroom — T8 18W neutral white for a comfortable atmosphere. Compact fixtures and shelving — T5 8W or 14W for narrow fitting profiles.

Maintenance: Lumilux tubes typically last 8,000–12,000 hours. Extend their life by avoiding frequent switching (each on/off cycle shortens lifespan), cleaning fixtures of dust every 3 months, and replacing in pairs — if a fixture holds two tubes, replace both together to maintain uniform brightness.

Why Nisko Lumilux? Nisko imports OSRAM — one of the world's leading lamp manufacturers — under the Lumilux brand for the Israeli market. Products arrive in protective packaging, comply with Israeli Standard SI 82, and feature tri-phosphor coating for consistent colour temperature throughout the tube's life.
