8.5 W 4-pin PL replacement lamp

This 8.5 W Philips Instafit lamp replaces horizontal PL compact fluorescents using the existing 4-pin G24q or GX24 ballast. It produces a 3000 K warm white output and carries the product code 458372. The clear envelope maintains the same light distribution as the original fluorescent tube.

Ballast-dependent operation

Because the lamp runs on the installed magnetic or electronic ballast, overall system power and flicker behaviour depend on that ballast rather than on the LED driver alone. Buyers who want a ballast-bypass or line-voltage LED solution should look for a different product type. The lamp is restricted from sale in 24 US states, so availability varies by location.

Questions about this item

Will the 4-pin G24q base need any maintenance after installation?

The 4-pin G24q base is a fixed electrical connection; no user maintenance is required once the lamp is seated in the fixture.

What limits continuous operation of the 8.5 W PL lamp?

The integrated driver and thermal design set the sustained output limit; the lamp runs at 8.5 W until the driver reaches its thermal ceiling.
