The Osram Lumilux T5 Short fluorescent bulb 8 W G5 Cool white 430 lm is a compact linear lamp designed for fixtures that accept T5 tubes with a G5 bi-pin base. Delivering 430 lumens at a colour temperature of 4000 K, this 8 W bulb produces neutral-cool white light with a Colour Rendering Index (CRI) of 80 and an expected operating life of up to 10,000 hours. Its slim short-T5 form factor makes it suitable for reduced-depth luminaires and retrofit applications where space is limited.

Advantages

The neutral cool white light (4000 K) supports clear visibility and a balanced colour appearance without excessive warmth or blue cast. A CRI of 80 ensures acceptable colour rendering for most indoor tasks. The G5 cap enables straightforward replacement in compatible fixtures, while the rated lifetime reduces maintenance frequency compared with high-turnover incandescent alternatives.
