Stop Guessing 5050 LEDs: The Fast Buyer’s Guide to Brightness, Heat & Beam Control

“Confirm the die map now—save yourself a midnight truckroll later.”

Problem — Quotes say “5050 SMD super bright,” but they don’t tell you what’s inside that 5×5 mm shell—RGB? singlewhite? dualCCT? You end up gambling with lux, heat, and color.

Agitate — Order the wrong reel and a retail aisle looks flat, a pixel wall looks blotchy, or a thin FR4 board runs scorchhot. Freight, labor, and apologies erase the pennies you “saved.”

Solution — Use the five checkpoints below. You’ll define what 5050 LED means, see what’s brighter than 5050, get real lumen numbers, know the default beam angle, and copy RFQ text that filters weak suppliers.

Paste this checklist into every RFQ. Each XGM pallet—RGB pixels or white flood—arrives bright, cool, and nearly RMAproof.

Search what does 5050 LED mean? and you’ll hit two extremes: “brightest RGB legend” vs. “inefficient dinosaur.” Reality is simpler: 5050 is only a footprint code—5.0 mm × 5.0 mm. Performance depends entirely on the die map, drive current, thermal path, and optics you pair with it.

You’ll meet three common personalities:

Tridie RGB 5050 — three tiny chips (R/G/B), each ~20 mA. Great for tight pixel pitch and saturated color effects.

Singledie white 5050 — one larger chip, 60–120 mA continuous. Good lumen punch per package, but it demands MCPCB or heavy copper to shed heat.

Dualdie CCT 5050 — two halfsize warm/cool dice, 25–35 mA per side, for tunable white shelves and troffers.

XGM’s 14year shipment data to U.S. buyers (New York, Midwest, Sun Belt) shows the same failures when teams treat 5050 as a guarantee rather than a geometry:

Underlux installs — RGB shipped where highflux white was needed.

Thermal runaway — white 5050 on 1oz FR4 spikes +25 °C board temp, browning phosphor early.

Spec drift — lab numbers at 25 °C quoted for aisles running 45 °C with 10 % driver ripple.

Below, each section gives a 30word hook, a buyerready snippet, an image slot, and a deeper dive you can paste into SOPs. Swap our placeholders with your teardown photos, LM80 pages, and Xray shots to satisfy EEAT and close audits fast.

1 ▸ What does 5050 LED mean?

A 5 mm × 5 mm package that can hold 3×RGB, 1×white, or 2×CCT dies. The die map—not the footprint—sets current, heat, and lumens.

TriRGB 5050s place three ~350 µm chips on one frame. Typical forward voltages: ~2.1 V (red) and ~3.2 V (green/blue), driven 18–20 mA each. These excel at color density and blending, not raw lm/W.

Singlewhite 5050s swap in a ~1.1 mm die. Common operating window: 60–100 mA continuous, 180 mA pulse with MCPCB. On thin FR4, heat climbs fast.

DualCCT 5050s combine two ~0.6 mm dice under a shared phosphor for 2700–6500 K tuning. Perfect for retail bays that change mood; not a substitute for RGB effects.

Copypaste RFQ filter

Package: 5050. Die map: 3×RGB / 1×White / 2×CCT (select one).

Thermal resistance (RθJB): ≤15 K/W (RGB), ≤10 K/W (white).

Lens: silicone preferred; epoxy only for indoor, lowUV.

Bins: white ≤3step MacAdam; RGB wavelength spread <2 nm.

Reliability: LM80 ≥10 000 h @85 °C/65 mA; 85/85 1 000 h, H₂S 3 ppm/72 h, −40↔+105 °C 1 000 cycles.

Traceability: Xray one reel per lot; pallet label must match LM80 lot.

Add a photolog line item—suppliers who can’t supply Xray and CSV logs usually can’t protect your warranty. See diemap checklist and traceability form.

2 ▸ What is brighter than 5050 LED?

For white light, 2835 flipchip (0.2 W) usually beats singlewhite 5050 on lm/W, $/klm, and board temperature. Keep 5050 for RGB density.

At 5000 K, 80 CRI, 100 mA:

Package Typical lm/W PCB requirement Approx. $/klm

2835 flipchip 175–185 2oz FR4 $0.84–0.90

3030 midpower 165–175 MCPCB $0.92–0.98

5050 singlewhite 130–145 MCPCB $1.05–1.10

Why the gap? 2835’s copper slug and short cavity cut thermal resistance (~2.4 K/W). Many white 5050s sit near 3.5 K/W, so driving harder adds heat faster than lumens. For troffers, coves, and shelves, 2835 wins. For pixel art, 5050 RGB still rules value per channel.

Field example—retail shelf, 24 V strip (96 LED/m):

Swap: 5050 white → XGM 2835 flipchip

Board temp: 54 °C → 46 °C

Field efficacy: 138 lm/W → 176 lm/W

Flicker index @5 %: 0.22 → 0.07

90day service calls: 9 → 1

Keep 5050 for RGB windows and gaming towers where 3in1 dies deliver tighter color at 12–16 mm pitch. Addressable 3535 pixels may close the gap—track pricing with pixelcost tracker.

3 ▸ How many lumens is a 5050 LED?

RGB: ~95–100 lm at 20 mA/channel. Singlewhite: ~45–50 lm at ~0.18–0.29 W—expect an extra ~8–10 % drop at 45 °C board temperature.

RGB 5050 @25 °C, 20 mA/ch (diffused):

Channel Radiant flux Visual lm

Red ~12 mW ~25 lm

Green ~24 mW ~60 lm

Blue ~6 mW ~10 lm

Composite — ~95–100 lm

Singlewhite 5050:

60 mA (≈0.18 W): ~28–30 lm

100 mA (≈0.29 W): ~45–50 lm (MCPCB advised)

On 1oz FR4, 100 mA commonly raises board temp +25 °C over ambient; efficacy falls and phosphor ages quicker.

Adopt a twotemperature test:

25 °C lab — validates bins and catalog claims.

45 °C board — mirrors U.S. aisle conditions.

Publish both in quotes. Teams that added a “45 °C flux” column reduced RMAs double digits because expectations matched reality.

For long runs needing >0.3 W per package, jump to 3030 or add heatsinking. Driving 5050 whites harder seldom pays; thermal tax beats lumen gain beyond ~120 mA.

4 ▸ What is the angle of 5050 LED lights?

Stock silicone dome ≈ 120° FWHM. Frost to ~150° for wallwash; clip TIR cups for ~30° punch—reserve ≥8 mm vertical clearance.

Wide beams blend RGB better, so 120° is a sweet spot for signs. Task lighting prefers 60° (glare control, higher center lux). Pathway and accent heads need ~30° to keep spill light down. Options:

Frost/sand dome: smoother halo, ~5 % flux loss, FWHM ≈150°.

Aluminum profile lens: quick 60° without extra height.

PMMA TIR cup: tight 30°, 2–3× center candela; needs space.

Narrow optics can expose color fringing if RGB die spacing exceeds ~0.4 mm. Always remeasure FWHM and Δu′v′ after lens changes.

Art wall, SoHo: frosted domes traded 5 % flux for perfect halos.

Trail bollards, Denver: 30° TIR cups tripled center lux but added 9 mm fixture height.
