FAQ
Questions Buyers Ask
Where are high-power bulbs used instead of regular A-bulbs?
High-power E27 bulbs (15–70W) serve high-bay-adjacent spaces, workshops, barns and street-light retrofits where a screw-in lamp must deliver much more light than a standard A60. They retrofit existing E27 sockets without fixture changes.
Die-casting or plastic-coated — which housing for my market?
Die-casting aluminum carries the full 20–70W range with the best heat dissipation for continuous high-load operation. Plastic-coated covers 15–40W at lower cost for price-sensitive markets and less demanding duty cycles.
Can I order mixed wattages in one container?
Yes — both housings and all wattage steps are mixable as one mixed-SKU order, with 50 pcs per inner carton.
What is the MOQ and lead time?
MOQ is flexible — trial orders and mixed-SKU containers are accepted. Lead time is confirmed per order at quotation; reference samples ship within 7 days.
Which certifications do these ranges carry?
Standard ranges are produced under CE and RoHS conformity, with test reports supplied per shipment.
