BREAKDOWN OF ULF44 VS SLFLASH

While both the Whelen ULF44 and SLFLASH are reliable universal flashers designed for emergency and utility vehicles, they cater to slightly different needs:

• Outputs:

  • The ULF44 features 4 outputs, suitable for basic or smaller lighting setups.

  • The SLFLASH provides 8 outputs, ideal for more complex or larger vehicle configurations.

• Inputs:

  • The ULF44 does not specify input channels, focusing more on basic flashing functionality.

  • The SLFLASH offers 8 inputs (5 activating, 3 non-activating), providing greater control and flexibility.

• Flash Patterns:

  • The ULF44 offers 62 Scan-Lock™ patterns, allowing for versatile yet straightforward operation.

  • The SLFLASH goes a step further with 64 programmable patterns, allowing users to customize their flashing sequence.

• Output Capacity:

  • The ULF44 can deliver up to 240 watts of total power.

  • The SLFLASH doubles the output capacity, offering 480 watts, making it better suited for larger lighting arrays.

• Application:

  • Choose the ULF44 for standard setups where simplicity and reliability are key.

  • Opt for the SLFLASH if you need enhanced customization, more outputs, and greater control over lighting configurations.

In summary, the ULF44 is a great choice for standard, straightforward setups, while the SLFLASH excels in more complex scenarios requiring additional inputs and outputs with programmable flexibility.
