A few good questions.

Which is better, the UltraFire WF-502BRX Red or the UltraFire LW20X PRO?

Neither wins for everyone. Choose the UltraFire WF-502BRX Red for predator and varmint hunters who prefer a red light and want the battery, mount, and remote switch included. Choose the UltraFire LW20X PRO for hunters and landowners who want a white long-range thrower with an optional remote switch and mount bundle.

Is there a UltraFire discount code?

Yes. Code SEBASTIANBASSOL gives 8% off on the official UltraFire store. Paste it at checkout and the saving shows in your order summary.

Who should skip the UltraFire WF-502BRX Red?

Look elsewhere if you need a high-output white light, long throw past 150 meters, or a light that can be used where lights on firearms are banned.

Who should skip the UltraFire LW20X PRO?

Look elsewhere if you want a wide flood, a light with one consistent set of published figures, or a pocket-size light.
