FAQ
<details open><summary>Question: What is the Ulanzi KL01 Mini Camera Flash used for?</summary><div>Answer: The <b>Ulanzi KL01, SKU L312</b>, is a compact manual xenon flash for adding brighter, more directional light to portraits, street photography, parties, product photos, and creative color shots. Its rotating filter wheel lets you change the color effect without carrying loose gels, while four manual power levels give you direct control over flash intensity.</div></details>

<details open><summary>Question: Which cameras are compatible with the KL01 flash?</summary><div>Answer: KL01 uses a universal single-pin hot shoe and works with most digital cameras that have a standard center hot shoe contact. It is not compatible with <b>Canon EOS 1500D, 3000D, or 200D Mark II</b> because those models do not have the required center contact. Check your camera's hot shoe before ordering, especially if it uses a proprietary interface.</div></details>

<details open><summary>Question: Does the KL01 support TTL, HSS, or wireless triggering?</summary><div>Answer: KL01 is a <b>manual single-pin flash</b>. You select 1/1, 1/2, 1/4, or 1/8 power on the flash itself; the official specifications do not list TTL automatic exposure or high-speed sync. No wireless trigger is included. Off-camera use would require a separately purchased trigger and receiver with a compatible center-contact hot shoe.</div></details>

<details open><summary>Question: How do the built-in color filters work?</summary><div>Answer: Rotate the filter wheel to switch between the standard flash output and seven built-in creative filters: <b>#85 CTO, #82 CTB, #206 Purple, #812 Rose, #102 Azure, #805 Medium Blue, and #504</b>. The filters are useful for warming skin tones, cooling a scene, or adding colored accents. Filtered output will be lower because each color transmits a different amount of light.</div></details>

<details open><summary>Question: Will the KL01 create a shadow with a long camera lens?</summary><div>Answer: Lens length and camera shape affect whether the lens blocks part of the flash. For cameras with a raised EVF housing, Ulanzi recommends lenses up to <b>10 cm / 3.94 in</b>. For flat-top cameras, the recommendation is up to <b>6 cm / 2.36 in</b>. Use a riser mount with longer lenses and test the frame before an important shoot.</div></details>

<details open><summary>Question: How powerful is the KL01 and how fast does it recycle?</summary><div>Answer: KL01 is rated at <b>GN10 at ISO 100</b>, with a 6500K ±5% unfiltered color temperature and CRI ≥96 at full power. Recycle time is approximately <b>2.5 seconds at 1/1</b>, 1.8 seconds at 1/2, and 0.8 seconds at 1/4; 1/8 power supports continuous flashing when the battery is sufficiently charged.</div></details>

<details open><summary>Question: How long does the battery last and how is the KL01 charged?</summary><div>Answer: The built-in <b>3.8V 400mAh battery</b> delivers up to 600 full-power flashes per charge under Ulanzi laboratory conditions. Charging takes approximately <b>1.5 hours</b> through the USB-C port using a 5V/1A power source. A charging cable is not included, and real flash count varies with power level, temperature, battery condition, and filter use.</div></details>

<details open><summary>Question: What is included, and what is the difference between the KL01 kits?</summary><div>Answer: The <b>Flash×1</b> option uses SKU <b>L312</b> and includes one KL01 mini flash plus a user manual. The <b>Flash×2</b> option uses SKU <b>L312+L312</b> and includes two flash units for two-camera use or a spare. Each flash measures 53.5 × 43 × 37 mm and weighs approximately 49 g. A USB-C charging cable is not included.</div></details>
