S3 Pro vs EDC2-DFT: how they differ
Size and weight
The RovyVon S3 Pro is the shorter light: 119 mm (4.69 in) against 150 mm (5.91 in), a difference of 31 mm (21%). At its widest point the RovyVon S3 Pro is 3 mm slimmer (29 vs 32 mm). Weights are published on different bases (RovyVon S3 Pro: 150 g listed; SureFire EDC2-DFT: 159 g listed), so they are not directly comparable.
Brightness and throw
The RovyVon S3 Pro is rated brighter: 2,800 lm maximum vs 700 lm for the SureFire EDC2-DFT, 300% more. For beam distance the SureFire EDC2-DFT reaches further: 632 m vs 130 m rated throw (386% more).
Battery
Both run on a removable 18650 battery, so spare cells work in either light.
Price
When we checked on Nov 4, 2026, the RovyVon S3 Pro was from $79.95 at batteryjunction.com and the SureFire EDC2-DFT from $287.00 at batteryjunction.com, so the RovyVon S3 Pro cost $207.05 less. Prices change often, so check the current price before you buy.
Type
Both are EDC lights in our catalog with a tube body.
Which should you buy?
Choose the RovyVon S3 Pro if you want a shorter light (31 mm shorter), a slimmer profile (3 mm narrower) and more output (2,800 lm vs 700 lm). Choose the SureFire EDC2-DFT if you want longer throw (632 m vs 130 m). We compare published size, weight, output, throw and battery only, not runtime, interface or build quality.
