Sea Frogs SF-L03 (1000 lm + Laser) — A Fun, No-Nonsense Review for Singapore Divers

If you night-dive Pulau Hantu, Jong, or Sisters’ Islands, you already know: a good torch is your superpower. Today we’re putting the Sea Frogs SF-L03 under the spotlight (pun intended) — a 1000-lumen dive torch with a built-in laser pointer that’s cheeky, compact, and surprisingly capable for the price.
TL;DR (for divers who are already late to board the boat)
What we like
Bright, wide 60° flood that’s perfect for local viz and buddy awareness.
Integrated laser for discreet pointing/communication underwater (more on safe/ethical use below).
100 m / IPX8 depth rating, aluminum build, and it comes with an 18650 battery + bag in the box.
Wallet-friendly.
Watch-outs
It’s a wide flood; not a tight wreck-peeking spot.
Listings claim “green laser,”
fixed 60° beam — assume no zoom.
Specs & Build: small body, big personality
Brightness & beam: 1000 lumens, 60° wide beam, 6500 K color temp; modes: High / Low / Flash plus Laser. Great for murky SG nights where a wider wash helps both viz and hand signals.
Depth rating: 100 m, IPX8. That’s more than enough for recreational night dives and most local profiles.
Battery & box: runs on 1×18650 (included on some listings) + spare O-ring and storage bag — handy for boat life.
Materials & size: aluminum alloy body, tempered glass lens; Ø36 mm × 135 mm, ~208 g (w/o battery). Feels reassuring but not brick-heavy.
How it feels in Singapore conditions
Night at Hantu/Jong: The 60° flood makes silt and backscatter kinder than a tight hotspot; you illuminate your working zone without blinding your buddy.
Buddy communication: The laser is a tidy way to indicate small critters without fin-waving. Keep it brief, never near eyes or cameras, and don’t “chase” animals with the dot. (General laser-safety and marine-life etiquette apply.)
Primary vs backup: As a primary for casual night fun, yes. For wreck penetration or hunting micro-details at distance, pair it with (or switch to) a tighter spot light (see options below).
Real-world pros & cons
Pros
Flood that flatters SG viz: Broad, even wash reduces “snow-globe” backscatter.
Laser built-in: Nice for guiding a buddy’s eye to boxer shrimps or tiny flatworms — responsibly.
Complete starter bundle: Battery, bag, spare O-ring = fewer add-ons.
Value for money
Cons
Not a long-throw spot: If you love tight beams.
Official spec points to a fixed 60°.
A quick word on laser etiquette (important!)
Never aim at eyes (divers, fish, turtles) or at cameras; short taps only to indicate, then off.
Be mindful that green wavelengths are more visible underwater — again, use sparingly and respectfully.
Follow your dive operator’s briefing; some sites and guides don’t allow lasers at all. (Common-sense conservation applies.)
Who should buy the SF-L03?
New night divers who want a forgiving flood at a friendly price.
Guides/spotters who occasionally point out critters without hand-waving. s
Photo buddies who already have a primary video light but want a compact utility torch with a pointer.
If your dives lean toward wreck interiors, line work, or strong current, reach for a tighter spot (Scubapro Nova 850 Tec) or pair the SF-L03 with a spotty backup.
Verdict (Singapore edition)
For Hantu nights, reef bimbling, and casual “show-and-tell,” the Sea Frogs SF-L03 is fun, functional, and frugal. It won’t replace a purpose-built spot for deep wrecks, but as a do-most light with a cheeky laser party trick, it’s hard to argue with the package.
