Philips PTB15D Emergency Inverter for Dimmable Type B TLED Lamps

The Philips PTB15D by Signify is a specialized 120-277V emergency lighting inverter designed specifically for phase-cut dimmable Type B TLED (Tubular LED) lamps, including the popular Philips Mains fit 4ft T8 series. In the event of a power failure, this inverter automatically switches to emergency mode, delivering up to 12.5 VA of phase-cut dimmed power for a minimum of 90 minutes. Its slim form factor allows for simplified installation, and its patented AC phase-cut dimming output ensures safe, reliable illumination for emergency egress without the need for a standard fluorescent emergency ballast.

Frequently Asked Questions

How does the PTB15D differ from the Bodine BTB15D?

Both models are manufactured by Signify and feature virtually identical internal specifications and emergency capabilities for Type B TLEDs. The PTB15D is marketed under the Philips brand name and is highly tailored for integration with the Philips MainsFit T8 lamp ecosystem, whereas the BTB15D carries the Bodine branding.

What is a Type B TLED?

A Type B TLED is a tubular LED lamp that features an internal driver and is wired directly to the main line voltage, completely bypassing the traditional fluorescent fixture ballast. The PTB15D is specifically designed to safely provide battery backup for these direct-wire LED tubes.

Can this inverter be used with standard fluorescent lamps?

No. The PTB15D is strictly designed as an emergency inverter for dimmable Type B TLEDs (like the MainsFit series) and cannot be used to operate or back up traditional fluorescent tubes or standard ballast-driven fixtures.
