1. How much shorter is the FL1M-06CW-4 compared to the standard model?
The FL1M-06CW-4 is specifically designed for ultra-shallow panels, offering a significant reduction in rear-body length over the standard 06CW-1.
2. Can I buy these metal indicator lamps in bulk?
Yes, they are available for sale in both individual units and bulk wholesale quantities.
3. What is the benefit of a concave head?
The recessed lens is shielded by the metal shell, protecting it from physical impacts and preventing accidental activation or damage.
4. Is the shell available in black?
Yes, we offer both chrome-plated silver (copper alloy) and black anodized metal shells.
5. What is the difference between pre-wired and pin terminals?
Pre-wired indicators come with factory-sealed 20cm leads, offering better waterproofing and faster installation. Pin terminals require you to solder your own wires or use connectors.
6. Are these indicators waterproof for outdoor use?
Yes, with a rating of IP65/IP67, they are fully dust-tight and can withstand heavy rain or temporary immersion.
7. Do you support custom voltages like 5V or 380V?
Absolutely. We can customize the internal resistors to match any voltage from 3V to 380V.
8. Does the package include everything for installation?
Yes, each lamp comes with a large O-ring, a metal gasket, and an M6 nut.
9. Are the threads smooth for installation?
Yes, we use precision CNC machining to ensure the M6 threads are smooth and easy to tighten.
10. What certifications do these lamps have?
Our 6mm metal indicators carry ISO9001, UL, CE, VDE, RoHS, and SGS certifications.
At FILN, we specialize in delivering precision-engineered indicator lights, push button switches, and rocker switches tailored to your unique requirements. While our products default to standard voltage ranges (12-24V and 110-220V), we understand that specialized applications demand flexibility.
Need a Custom Voltage Solution? Simply inform us of your desired voltage specifications (e.g., 5V, 48V, or non-standard ranges), and our engineering team will craft a solution within 10-15 business days.
✅ Expertise You Can Trust: Over 20 years of experience in industrial-grade electronic component production.
✅ End-to-End Customization: From voltage adjustments to bespoke designs (shape, color, IP rating), we adapt to your needs.
✅ Quality Guaranteed: All custom orders undergo rigorous testing to meet CE/RoHS/IP65 standards.

The 6mm Metal Indicator Lamp works exactly as described and the shorter body fits our compact device beautifully. However, shipping to our US facility took almost 25 days. Additionally, the yellow LED we tested in the same batch feels significantly less bright compared to this vibrant green/blue indicator.
Dear Customer, thank you for your candid review. We sincerely apologize for the international shipping delays you experienced. Regarding the brightness, our 6mm Metal Indicator Lamp uses premium, high-efficiency chips; however, due to wavelength variances, green/blue lights naturally appear more vibrant than yellow. We can easily customize the internal resistor and voltage specs to boost the yellow LED brightness for your specific equipment. Please reach out to our team so we can arrange optimized replacements for you!

6mm 메탈 램프의 단축형 디자인은 공간 절약에 훌륭하지만, 해외 배송이 생각보다 너무 오래 걸렸습니다. 그리고 샘플로 구매한 황색(Yellow) 램프는 녹색 제품에 비해 광량이 조금 부족한 느낌이 듭니다. 공장 피드백은 빠릅니다.
