Which should you buy?

Choose the Sofirn SC33 if you want a shorter light (5.4 mm shorter), a slimmer profile (2 mm narrower) and more output (5,200 lm vs 1,800 lm). On the specs we track, the Sofirn SC33 is ahead or level everywhere; the Fenix LD35R makes sense mainly if its price, interface or a feature we don't track suits you better. We compare published size, weight, output, throw and battery only, not runtime, interface or build quality.
