Product Description

Q1) What is Probe Start Lamp & Pulse Start Lamp? Probe Start Lamp: A traditional or probe start metal halide lamp has an internal starting electrode or probe. A high open circuit voltage from the ballast initiates an arc between the two starting electrodes at one end of the arc tube. Once the lamp reaches full output, a bi-metal switch closes to short out the probe and discontinues the staring arc. Pulse Start Lamp: A pulse start lamp has an improved arc tube design and an increased fill pressure. An ignitor in the pulse start system delivers a high voltage pulse directly across the lamp's operating electrodes to start the lamp eliminating the probe and bi-metal switch needed in probe start lamps. Q2) How do I know my Lamp type? It is quite simple. Pulse Start Lamp has an oval shaped arc tube as shown below. If your lamp has it, yours is Pulse Type. Otherwise, Probe Type. Q3) Are the bulb types interchangeable? No. Pulse-start lamps and probe-start lamps use a different ballast system. Pulse-start lamps will likely fail to start with probe-start ballasts. If the lamp does start, it will likely give inconsistent and lower light. So if you are changing lighting from probe-start to pulse-start lamps, change the luminaries too 175W 10K Metal Halide Aquarium Bulb E39 Watt: 175W Kelvin Temp: 10000 Kelvin Size:8.5" x 1.8 (H x W) Base: E39 Mogul Base Shape: T-Bulb Shape Universal Burn Position Single-Ended Metal Halide Bulb
