Philips Lighting 473934 – Frequently Asked Questions

1) Can I install this Philips 13W T8 LED tube in my existing fluorescent fixture without rewiring?
That is the point of the InstantFit design. The 13W T8 LED tube runs off an existing fluorescent ballast, and Philips states compatibility with over 350 ballasts and drivers, with a ballast bypass option if you'd rather go direct wire later. It uses the same G13 medium bi-pin base as the fluorescent lamp you're pulling out, so it drops into the existing sockets.
2) Will a 277V ballast run this Philips InstantFit LED tube?
Yes. Nominal voltage on this T8 LED tube is 277V, which is the common commercial and industrial branch circuit in North America. The ballast also needs to fall inside the tube's operating window: 20,000 to 120,000 Hz output frequency and a lamp current between 130 mA and 400 mA. Instant start and programmed start electronic ballasts in that range are what it is built to sit on.
3) Can I use this Philips T8 LED tube in an unheated warehouse or a covered parking garage?
Ambient range is -20C to 45C, so an unheated warehouse, a loading dock or a covered parking deck is inside spec in most climates. Below -20C or in an enclosed fixture that pushes ambient past 45C, look at a lamp rated wider. Case temperature tops out at 50C. Stored product tolerates -40C to 65C, which covers an unconditioned stockroom.
4) Will 13W be bright enough to replace the 32W fluorescent tubes we have now?
2100 lumens out of 13W, which works out to 161 lm/W. A standard 32W T8 fluorescent is typically in the 2800 to 3000 lumen range when new, but it depreciates hard and loses output in a dirty fixture, so on a one-for-one swap most warehouse and office spaces land at similar delivered light. Where the existing layout is already marginal, do a photometric check before committing the whole building.
5) Is this LED tube actually dimmable, or do I need a different lamp for dimming circuits?
It is a dimmable T8 LED tube, so it can sit on a dimming system rather than needing a separate SKU. The dimming has to come from the ballast driving it; the tube follows the ballast it is installed on, so the existing dimming ballast and control has to be one Philips lists for InstantFit operation.
6) Does this Philips LED tube qualify for a utility rebate?
It carries DLC Standard listing, which is the qualification most utility prescriptive rebate programs require for linear LED replacement lamps. Bring the DLC listing and the wattage to your utility program administrator; the rebate amount itself is set by the program, not by the lamp.
7) How much light do I lose over the life of this tube, and how often will I be relamping?
Rated life is 70,000 hours, and at end of that rated life the lamp is still putting out 70 percent of its initial 2100 lumens. Design the layout to the maintained number, not the initial one, if you need a held footcandle level. For maintenance planning, at 12 hours a day that rated life is roughly 16 years of operation. It is also rated for 50,000 switching cycles, so occupancy-sensor-controlled spaces are fair game.
8) Will these tubes match color when I only replace some of the fixtures in a room?
Color consistency is held to under 6 SDCM, so tube-to-tube variation within the same color temperature is tight enough that a partial relamp in the same room will not show an obvious color split. Beam angle is 180 degrees, the same downward distribution a fluorescent tube gives in a troffer or strip, so the pattern on the floor does not change either.
9) Is this Philips LED tube RoHS compliant for a green building or LEED project?
Yes, the 13W T8 LED tube is EU RoHS compliant, and unlike the fluorescent lamp it replaces it contains no mercury to manage at disposal. Combined with DLC Standard listing, it covers the documentation most sustainable-procurement specs ask for on a lamp line item.
