Case of 50 compact fluorescent bulbs

This case contains fifty 15 watt T4 compact fluorescent bulbs with a 4-pin G24q-2 base. Each bulb produces 1,125 lumens of cool white light at 4,100K while consuming 15 watts to replace a traditional 60 watt incandescent lamp. The bulbs are dimmable and rated for an average lifetime of 20,000 hours.

Suits commercial relamping projects

Buyers needing a large quantity of identical cool white lamps for recessed downlights or wall sconces with compatible 4-pin ballasts will find this case convenient. Those requiring a warmer colour temperature, a screw-in base, or instant full brightness in cold environments should consider alternative lamp types.

Maintains output over long operating periods

Under sustained operation the lamps reach full brightness after a brief warm-up and deliver stable 1,125 lumen output for the rated 20,000 hour life. Dimming performance depends on the matched ballast, and frequent short cycles may reduce the achieved lifetime compared with continuous running.

Questions about this item

What type of ballast must the fixture already have for these 4-pin G24q-2 bulbs to operate?

The fixture needs a compatible electronic ballast designed for 15-watt compact fluorescent lamps with a G24q-2 base.

Can I mix these 15-watt T4 bulbs with older 18-watt or 26-watt CFLs on the same dimming circuit?

No, different wattages require different ballasts; each lamp must match its ballast rating to avoid flicker or early failure.

How can I confirm the 4100 K cool white output is correct once the case of 50 is installed?

Verify the 1,125-lumen rating on the packaging and check for a steady, neutral-white glow without green or pink tint.
