Overview
HongYu Bulb's G4, G9, and spotlight range covers the small-lamp applications that filament bulbs cannot: display-case G4 capsules (12V), mains-voltage G9 loops, and MR11/MR16/GU10 spotlight replacements. COB chip designs eliminate the visible hotspot common in SMD clusters. CE and ETL listed, 1.1W to 5W, 3000K to 4000K, beam angles from 24° (narrow spot) to 60° (wide flood). Ra 80 and Ra 90 available.

Why Buyers Choose This Series
⭐ COB design — no hotspot through the diffuser lens, the failure mode that ends repeat orders
SMD-cluster spotlight bulbs often show individual LED dots through a frosted diffuser — visible to the eye and obvious in display-case jewellery and watch lighting. HongYu Bulb's COB models use a single-chip design that produces a smooth, even beam with no visible emitter pattern. For retail display and hospitality applications where the light source is visible to the customer, this is not a cosmetic preference — it is a functional requirement that buyers state explicitly in their RFQs.

FAQ
G4 vs G9 — what is the difference?
G4 has two pin contacts 4mm apart, runs on 12V. G9 has looped pins, runs on 230V — no transformer needed.
Do G4 LEDs need a special transformer?
G4 LEDs require an AC 12V transformer (not DC). DC transformers cause flickering or failure.
What beam angles are available?
24°, 36°, and 60°. High CRI (Ra 90/95) available for display use.
MOQ?
500 pcs per item. Mixed orders from 300 pcs per model.
