Lighting batteries and lights

Models in this category

The 2 models are SL-272A and HDL-40AI. The SL-272A is a video light battery with a 6.8V voltage, a power figure stated as 40Wh in the original, a DC 15V / 3A adapter, a colour temperature range of 3200K-5600K, and compatibility with V-mount batteries. The HDL-40AI is a ring light with a built-in battery stated as 3.7V / 2500mAh / 18.5Wh in the original, a weight of 635g, and operating, humidity and storage ranges. Both model pages transcribe their figures exactly as stated, including the units as written.

• HDL-40AI — built-in battery 3.7V / 2500mAh / 18.5Wh, 635g, operating 0-35 C, humidity 20%-80%, storage -10-50 C.

Reading the figures exactly as stated

Two figures on these pages deserve care. The SL-272A's power figure is stated as 40Wh in the original, and this site keeps it as 40Wh, not restated in watts, because changing the unit would change the meaning. The HDL-40AI's built-in battery is stated as 3.7V / 2500mAh / 18.5Wh in the original, and this site keeps all three figures as stated, without adding an explanation for them, because none is given in the evidence. A buyer who needs clarification should ask in the inquiry.

Colour temperature describes the light's colour, from warm to cool: the SL-272A's range of 3200K-5600K covers warm to daylight. The ring light guide explains lighting choices in general terms, and the model pages give the per-model specifications.

What to confirm before ordering

Name the model, the exact lighting equipment it must serve, the quantity you have in mind, and the market you sell into. Ask for the specification for the exact model, the minimum order quantity, the lead time with its meaning, the warranty terms, and the certificates that apply to your market, by name, with documents attached.
