Compact fluorescent bulb for 2700K lighting

This 13-watt double-tube fluorescent bulb produces 780 lumens at a warm 2700K colour temperature with a colour rendering index of 82. It is rated for 10000 hours of operation and suits general indoor fixtures that accept a two-pin base.

Check fixture base and voltage before ordering

Verify that the luminaire uses a two-pin socket compatible with this double-tube design and that the supply voltage matches the lamp rating. The physical dimensions must fit within the shade or enclosure without contacting the glass.

Replaces older 13-watt compact fluorescents

The upgrade is worthwhile when the existing lamp has degraded below 780 lumens or shows colour shift away from 2700K. It does not suit fixtures requiring higher lumen packages, different colour temperatures, or alternative base types.

Questions about this item

Does the CF13D/827 bulb come with a ballast or do I need to buy one separately?

The bulb is a 13W 2-pin compact fluorescent; the required ballast is built into the compatible fixture, not included with the lamp.

The model code shows 827 and the specs list 2700K and 82 CRI — what do those numbers tell me about the light quality?

827 means 2700K warm white colour temperature and a colour rendering index of 82, giving a warm tone with decent colour fidelity for living areas.

In a real fitting the box says 780 lumens and 10000 hours — what does that actually mean for daily use?

You get 780 lumens from 13 watts, and at three hours per day the rated 10000-hour life equals about nine years before replacement.
