Frequently Asked Questions

Q: Do these 1W LED chips require a heatsink?

A: Yes. For best performance and maximum lifespan, these 1W high power LED chips on aluminum star PCB should always be mounted on an appropriate heatsink. The aluminum PCB helps dissipate heat, but pairing it with a heatsink ensures the chips run at optimal temperature and last their full 100,000+ hour rated life.

Q: What driver or power supply do I need for these warm white LED emitters?

A: Each chip requires a DC forward voltage of 3.4V–3.6V and a forward current of 300mA–350mA. Use a constant-current LED driver or power supply that matches these specifications. Running multiple chips in series or parallel will require a driver rated accordingly. Do not connect directly to mains voltage.

Q: Are these LED chips suitable for outdoor and garden lighting?

A: Absolutely. These 1W Epistar LED chips are widely used in garden lights, wall lamps, outdoor signage, and landscape illumination. Just ensure the fixture provides adequate weatherproofing and that the PCB is properly secured to a heatsink for reliable outdoor performance.

Q: What's the difference between the 10, 50, and 100-piece packs?

A: All three pack sizes contain the same 1W warm white LED chips on 20mm aluminum star PCBs. The different quantities simply allow you to choose based on your project size — 10-piece for small DIY builds, 50-piece for medium projects, and 100-piece for large installations or bulk stock.
