This board solves that at the cost of current draw. Running 640 LEDs at 12V DC pulls 1.08A per metre, the highest current figure in the low-voltage family, which limits practical run length more than any other model in the range. It is not the strip to specify for a long cove or perimeter run; it is the strip to specify when a handful of very short, precisely measured sections need matching to the millimetre.
At 640 COB LEDs per metre, this is the highest density product in the D series COB range — a specification that exists for one reason: the 12.5mm cut interval it enables. Where compartments are measured in tens of millimetres rather than whole centimetres — small jewellery drawers, narrow display niches, tightly spaced shelf dividers — a strip that only cuts every 25mm or 50mm cannot match the length precisely.
Output is 1400 lm/m from 13W, matching the top-tier figure elsewhere in the 8mm family despite the shorter practical run length. The strip is 8mm wide, rated IP20 for indoor use only, energy class F, and offers six colour temperatures from 2700K to 6500K specified at order.

Steps:
Run length limitation: at 1.08A per metre, this is the highest current draw in the low-voltage D series. Keep individual runs short — this board is designed for precisely matched short sections, not long continuous perimeters. For longer runs, specify a lower-density, lower-current model such as the 320 or 480-LED boards.

Q: When should this 640-LED strip be specified over the 512-LED board?
A: When compartments are shorter than the 512-LED board's cut interval can accommodate precisely. At 12.5mm, this board halves the granularity of the 25mm-cutting 480-LED strip, making it the choice for very small, tightly measured sections rather than general cabinet runs.
Q: Why is the current draw so much higher than other 12V boards?
A: 640 LEDs per metre is the highest density in the D series, and density drives current draw at a given voltage. At 1.08A per metre, practical run length is shorter than lower-density boards. This model is not intended for long continuous runs — use it for short, precisely matched sections only.
Q: Is there a 24V version at this density?
A: Yes, the 24V 640-LED board offers the same density with lower current draw and a wider 25mm cut interval at higher output (1800 lm/m). Choose 24V for longer runs at this density; choose this 12V version specifically for the finer 12.5mm cut precision.
Q: What is the maximum recommended run length for this strip?
A: Given the 1.08A per metre draw, keep individual sections short — a few metres at most from a single feed point. This board is engineered for cut precision on short sections, not extended perimeter runs.
Q: Does the fine cut interval affect light output per section?
A: No. Each cut section functions as a complete circuit segment at full rated brightness; the cut interval only determines the minimum incremental length adjustment available.
Q: What are the MOQ and lead time?
A: MOQ is 50 sets, lead time 15–21 days. Supplied on 5m reels, 100 reels per carton totalling 500m, shipped from Guangzhou or Shenzhen.
