EiKO Q300T3/CL/130V – Frequently Asked Questions

1) Will an EiKO Q300T3 R7s halogen bulb fit my double ended fixture, and what length do I need to check?
The Q300T3/CL/130V measures 119.10 mm (4.69 inches) maximum overall length with a maximum overall diameter of 10.00 mm (0.39 inch). R7s double ended fixtures hold the lamp between two spring-loaded contacts, so the socket-to-socket span has to match that 119.10 mm end-to-end length, not just the base type. Measure the old lamp or the gap between contacts before ordering: a 78 mm or 189 mm R7s fixture takes a different lamp even though the base designation is identical.
2) Can I mount a 300W R7s double ended halogen bulb vertically in a wall sconce or uplight?
No. This 300W T3 halogen is rated for horizontal burning position only. Running a linear halogen tilted or vertical lets the C-8 coiled filament sag and puts uneven heat on the quartz envelope, which shortens life well short of the 2,000 hour rating. If the fixture holds the lamp on an angle, use a lamp rated for universal or vertical burn instead.
3) My fixture is on 120V - can I use a 130V 300W halogen lamp in it?
Yes, and it is the usual reason a maintenance buyer picks the 130V version. The Q300T3/CL/130V is rated at 130 volts, so on a 120V circuit it runs under its design voltage. That means less filament stress and longer service than the same lamp run at its rated volts, with slightly lower light output than the 4,800 lumen rating, which is measured at 130V. For work lights, security floods, and anything up a ladder, that trade is normally worth it.
4) Can I put a 300W T3 halogen bulb on a dimmer?
The Q300T3 is listed as non-dimmable, so specify it for switched circuits. If you are replacing a lamp in a fixture that is already on a dimmer or an occupancy sensor with a dimming output, that is a reason to look at a different lamp rather than assume the R7s base makes them interchangeable.
5) How often will I be relamping 300W halogen work lights, and should I just go LED instead?
Plan on 2,000 hours per lamp. Run 10 hours a day and that is roughly 200 days, so a job-site or security fixture burning all night gets relamped once or twice a year. The Q300T3 is not Energy Star qualified and carries no DLC Standard or DLC Premium listing, so it will not draw utility rebates the way a qualifying LED retrofit does. Halogen still earns its place where you need instant full output at 2850K, dead-accurate color, and a fixture that already takes an R7s lamp with no rewiring.
6) Is a 300W R7s halogen still legal to sell in California?
The Q300T3/CL/130V is exempt from California Title 20 lamp regulations, so it is not caught by the state general service lamp restrictions. That matters if you are stocking MRO shelves for properties in California and have had other halogen lamps disappear from the supply chain.
7) How much light does a 300W double ended halogen put out, and what does 2850K look like?
4,800 lumens at 130V, which is why these show up in construction temporary lighting, shop and work areas, and security floods where you want a lot of output from one small lamp. The color is 2850K, a warm white close to old incandescent, so it blends with existing incandescent and halogen fixtures rather than reading blue against them. It is a general use lamp, not a specialty or photo-spec type.
8) Can I handle a quartz halogen tube with bare hands when I change it?
Don't. The Q300T3 has a clear quartz envelope running at 300 watts, and skin oil left on quartz causes devitrification at that surface temperature, which leads to early failure or a cracked envelope. Use a cloth or glove, and wipe the tube with alcohol if you touch it. Also let the fixture cool before you spring the lamp out of the R7s contacts.
