Philips 146332 57W Triple Tube Lamp

This Philips 146332 compact fluorescent bulb uses a 57W triple-tube design with a 4-pin GX24Q-5 base. It delivers 3900 lumens at a 4100K cool white colour temperature and a CRI of 82. The rated life is 4300 hours. It fits commercial recessed or surface-mounted fixtures that accept this specific base and wattage.

Suits offices needing high-output cool white light

This lamp suits offices, retail spaces or institutional areas that require the 3900 lumen output of a 57W triple-tube format in a 4100K colour. It is not for fixtures limited to lower wattages such as 24W or 32W models, nor for sockets that accept only 2-pin bases. Buyers needing dimmable operation or a warmer colour appearance should look at other options.

57W rating and GX24Q-5 base determine fit

The single specification that decides compatibility is the 57W power rating combined with the GX24Q-5 4-pin base. The ballast must be rated for 57W and the socket must match this exact base type; a 24W or 32W ballast will not operate this lamp and a 2-pin socket will not accept it.

Questions about this item

Will the GX24Q-5 4-pin base fit my existing fixture?

This bulb uses a GX24Q-5 4-pin base. Check that your fixture socket matches this exact base type before purchasing.

How do I install the 4-pin PL-T bulb without damaging the pins?

Align the four pins with the socket keyways and press straight in until the bulb seats firmly. Do not twist; the 4-pin base is a push-fit design, not a twist-lock.

When should I replace this 57 W fluorescent bulb?

Rated life is 4300 hours. Plan replacement when light output drops noticeably or the tube fails to start, typically near the rated hours.
