(8 Pack) PLC-13W 835 4 Pin G24q-1 Compact Fluorescent Bulbs

In this review the writer tested an 8 pack of PLC-13W 835 double-tube compact fluorescent bulbs to see whether they meet the common needs of household and light commercial fixtures. The bottom line: these bulbs are best for anyone who needs a straight replacement for common 4-pin GX24q-1 sockets and wants a consistent soft white 3500K output with long life and good value. The reviewer found installation simple, the light output comfortable for bathrooms and utility rooms, and the energy savings noticeable compared with older incandescent options.

Key Features

• 800 lumens light output: Provides reliable brightness that improves visibility in sinks, mirrors, and work areas without feeling overly harsh.
• 13 watts energy used: Uses a fraction of the energy of equivalent incandescent bulbs while delivering similar usable light for daily tasks.
• 3500K soft white: The color temperature produces a neutral soft white that avoids a yellow cast and suits bathrooms and kitchens well.
• 10,000 hours average lifetime: Long rated life reduces replacement frequency and maintenance for fixtures with GX24q-1 bases.
• 4-pin GX24q-1 base: Designed to be a direct fit for fixtures replacing models such as Philips 38327-3 and GE 97596.
• 82 CRI: Color rendering is good for general tasks, making skin tones and surfaces appear natural under these bulbs.

Who It's For

This pack is aimed at homeowners, landlords, and small businesses that need multiple identical replacements for fixtures using a 4-pin GX24q-1 base. It is particularly useful for bathrooms, vanity lights, closets, and utility areas where a neutral soft white is preferred over warm yellow or cool blue light.

Those who should look elsewhere include people who need dimmable bulbs, very compact lengths under 5 in, or a different color temperature such as daylight 5000K. Also, buyers who prefer LED technology for instant full brightness and even longer life may choose LED alternatives instead.

Pros & Cons

Pros

• Good value for an 8 pack that covers several fixtures at once and reduces trips to buy replacements.
• Consistent soft white 3500K color that customers report is not yellow and is pleasant for bathrooms.
• Easy installation: customers say the bulbs "plug right in" to GX24q-1 bases and function as direct replacements.
• Long rated life and efficient 13 watt draw help lower operating costs over time.

Cons

• Not dimmable and requires a compatible 4-pin ballast or fixture, so it is not universal for all sockets.
• As a fluorescent option, it may not reach full perceived brightness instantly in very cold environments compared with LEDs.
