ULANZI SL02 Mini Flash Speedlite Video Light GN8 6500K Hot Shoe Mount Portable Camera Flash Speedlight
Quick take
ULANZI SL02 is a pocket-friendly hot-shoe mini flash with a built-in rechargeable battery, plus a continuous video light mode. It is best for manual fill light, quick night/portrait accents, and travel setups where you want something small, not a full-size flash system. The main caveat is compatibility and control, it works only with cameras that have a single-contact hot shoe, and it has no TTL or automatic mode.
Pros and cons
Pros
- Ultra-compact design (about 36g), easy to carry for everyday or travel use.
- Manual-friendly control with 4 brightness levels, useful for fill-light style results.
- Built-in rechargeable battery with USB Type-C charging, includes both flash and continuous video light modes.
- 6500K flash color temperature and high color rendering index claims (helps keep light more natural-looking).
Cons
- No TTL or automatic exposure, you need to dial it in yourself.
- Not compatible with some popular camera models, it requires a single-contact hot shoe.
- Small size means it is intended for lighter, fill-style use rather than overpowering daylight.
What buyers think
Buyer-review themes are consistent around portability and ease of use. Multiple shoppers describe it as a practical small flash for everyday or “carry it in a bag” shooting, and they like that they can keep it mounted and ready without the bulk of larger speedlights. Reviewers also generally frame the output as “not super strong,” but sufficient for fill light, low-setting use, and situations where a subtle boost is the goal. Evidence on battery performance shows up as a plus, with users mentioning good runtime relative to the unit’s size. Overall, buyer feedback is positive when the camera setup is compatible and when expectations match its manual, compact design. Buyer-review evidence is limited in detail about long-term reliability beyond normal usage impressions.
What you get and how it works
The SL02 combines a mini flash and a continuous video light in one hot-shoe device. You can switch between flash mode and video light mode, then select from four power or brightness levels (1/1, 1/2, 1/4, 1/8) for more control over how much light you add.
Flash mode details
- Manual operation (no TTL or automatic exposure).
- 6500K flash color temperature (±300K).
- Guide number rating: GN8 at ISO100.
- Recharge and runtime claims include up to 500 full-power flashes (when used at full power).
- A flash sync limit of up to 1/250s is recommended for best results.
Video light mode details
- Continuous output for video or steady illumination.
- Color temperature of 5600K for the video light mode.
- Color rendering index is listed as 95.
- Power output is listed as 1W.
- Runtime is listed as up to 1 hour 25 minutes of continuous use, with charging via USB Type-C.
Compatibility is the make-or-break factor
This mini flash is designed for a single-contact hot shoe. If your camera uses a different hot-shoe type, it may not trigger properly. The brand also lists specific models it supports, and it explicitly calls out certain cameras as not compatible (including several Sony, Canon, and some Fuji models). Before buying, confirm your camera has a single-contact hot shoe, then cross-check your model name against the supported list.
Silent mode and shutter type notes
If your camera uses silent shooting, turn it off when using this unit. Some cameras may also require changing the shutter type to mechanical to get consistent flash triggering, then setting the flash sync setting to manual mode (M) so the SL02 fires as expected.
Pros and cons for real-world use
Best for
- Photographers who want a compact hot-shoe flash for fill light, night portraits, and on-the-go shooting.
- Manual flash users who do not need TTL automation.
- Content creators who want a small continuous light option in the same footprint as a mini flash.
Who should avoid it
- Anyone needing TTL, automatic flash exposure, or camera-to-flash metering integration.
- Buyers with a camera that does not have a single-contact hot shoe, or whose model is listed as incompatible.
- People trying to overpower bright daylight or replace a high-power flash kit, since its compact GN8 rating is geared toward subtle assistance rather than dominating light.
Battery, charging, and portability
The SL02 uses a built-in 250mAh 3.7V polymer battery, charged through USB Type-C (Type-C, 5V 1A). It also supports using the unit while charging, which is a practical advantage if you shoot for long sessions or create multiple takes. In video light mode, runtime is rated up to 1 hour 25 minutes, and flash mode is rated up to 500 full-power flashes.
Weighing about 36g, it is one of the easier mini flashes to justify for everyday carry, especially if you already use a small mirrorless body and want a lighting accessory that does not become “a whole thing.”
Price and availability
This model is positioned as a low-cost mini flash and continuous light accessory. If you are shopping under the assumption that it will replace a full-size speedlight, you may feel underwhelmed. If you buy it as a compact fill-light tool for manual control, the price-to-features can make sense.

Verdict
Buy the ULANZI SL02 if you want a tiny hot-shoe flash/video light for manual fill light, travel, and small lighting boosts, and you confirm your camera has a single-contact hot shoe. Skip it if you need TTL automation or if your specific camera model is on the incompatible list. It is a simple, compact lighting add-on that tends to satisfy shoppers who match expectations to its size and manual-only operation.
FAQs
Does the ULANZI SL02 support TTL?
No. It is manual-only, so you will need to set exposure and brightness yourself using the 4 power levels.
Will it work with my camera?
It requires a camera with a single-contact hot shoe. Confirm your camera’s hot-shoe type and verify your exact model against the supported list, since some popular cameras are listed as not compatible.
What brightness levels does it have?
It provides four levels (1/1, 1/2, 1/4, 1/8) for both flash brightness and continuous light control.
How long does it last on a charge?
Charging is via USB Type-C (5V 1A). Runtime is rated up to 500 full-power flashes, and up to about 1 hour 25 minutes in video light mode.
Is it good for portraits and night fill lighting?
Yes, it is designed for that kind of use, especially as a fill light or subtle extra illumination. If you need to overpower daylight or create heavy, directional lighting at distance, you may want a higher-powered flash system instead.

Nikon SB-700 AF Speedlight Flash for Nikon Digital SLR Cameras, Standard Packaging
The Nikon SB-700 is a compact, feature-rich shoe-mount flash built for Nikon Creative Lighting System (CLS) users who want more than a built-in flash, plus reliable wireless control. Expect fast recycle times, strong i-TTL performance on compatible Nikon DSLRs, and useful onboard diffusion and filters, with the main caveat being compatibility limits outside Nikon CLS ecosystems.
NEEWER TT560 Camera Flash Speedlite Compatible with Canon Sony Nikon Panasonic Olympus Pentax and Other DSLRs
The NEEWER TT560 is a manual, shoe-mount speedlite built for photographers who want reliable manual flash control, fast recycling, and flexible head movement. It also works as an optical slave for off-camera setups, but it does not support TTL or HSS, and compatibility depends on having a single-contact hot shoe (not the ZV-1F).

A compact TTL speedlite kit designed for Canon users who want one on-camera flash that can also act as a wireless trigger through the included X5C. It supports TTL, HSS up to 1/8000s, and 2.4G wireless control (up to about 80m), but it is not compatible with Canon R50/R50V.
Godox IT32 TTL Camera Flash for Nikon with X5N Trigger & Diffuser kit

The main tradeoff is modest guide number power (GN18) versus larger studio-oriented flashes.
