Porcelain
Overview
Not all white bulbs diffuse light the same way. Four distinct processes exist in the market, and the quality difference is substantial. Frosted (acid-etched): inner glass etched to scatter light — almost no lumen loss, but glare remains and the filament is still partially visible. Opal-white (internal powder spray): white powder baked inside the glass — 10–20% lumen loss, 200K CCT drop, noticeably softer but the outer surface stays shiny. Sand frosted (external sandblast): matte grey exterior — lumen loss 80–90%, strong diffusion. Porcelain (external matte-white spray): the finish used by premium European lighting brands — lumen loss 80–90%, CCT drop 100–200K, but the diffusion quality is the highest of any process: fully uniform, zero visible filament, comfortable to look at directly even at full brightness. HongYu's EU porcelain range uses this process, CE + ERP + RoHS certified for 230V, available in Ra 80, Ra 90, and Ra 95.

Why Buyers Choose This Series
⭐ The premium diffusion standard — and why European lighting brands pay more for it
The industry ranking from weakest to best diffusion is: Frosted (acid-etch) → Opal-white (internal powder) → Sand frosted (external sandblast) → Porcelain (external matte-white spray). Porcelain delivers complete scatter — the kind that eliminates all glare, makes the bulb face look uniformly bright at any angle, and allows direct eye contact at full brightness without discomfort. The 80–90% lumen reduction is the physics cost of that quality, and it is the reason high-end European brands specify it: their customers notice the difference immediately when they see a porcelain bulb next to a standard frosted one. HongYu also offers Ra 95 in porcelain — a combination most factories cannot produce, requiring tuned LED chips to compensate for the spectral shift caused by the coating.

FAQ
What is the difference between porcelain, frosted, and opal-white?
Four finishes exist, ranked weakest to best diffusion: Frosted (acid-etch, almost no lumen loss but poor diffusion) → Opal-white (internal powder, 10–20% lumen loss) → Sand frosted (external sandblast, 80–90% loss) → Porcelain (external matte-white spray, 80–90% loss, best diffusion quality).
Is CRI 95 available in porcelain?
Yes — Ra 95 available in porcelain on A60, G95, and G125. This is unusual — most factories only offer Ra 95 in clear glass.
MOQ?
500 pcs per item. Mixed orders from 300 pcs per model.
Are all shapes CE + ERP certified?
Yes — all models carry CE, ERP, and RoHS certification.
