Tronic Sodium Bulb E40 250W

Our review

This is a Tronic sodium bulb rated at 250 watts with an E40 base, the wide screw fitting common on larger outdoor and industrial light fixtures. Sodium lamps of this type are typically chosen where a warm, high-output light is needed across a broad area, such as yard lighting, security floodlights or workshop fittings, rather than for indoor rooms where colour accuracy matters. Before buying, check the wattage and cap your fixture is rated for, since an E40 holder will not accept smaller bases and the ballast or control gear must match the lamp type. It also helps to confirm the fitting's maximum wattage so you do not overload it. Compared with LED or metal halide alternatives, sodium lamps generally run warmer in colour and take a short time to reach full brightness, so weigh that against your needs. The listing itself gives no further specifications, so treat the wattage and base as the key details to verify. Available on Sokonia.
