Circular Blue LED Reactor 90 W with Fan

Official SmartChemSynth product image for the Circular Blue LED Reactor 90 W with Fan (SCS-PR-B-F). Enter lux manually. Product specifications list blue LED output up to 440 nm, a stainless-steel cage, 96 mm ID × 140 mm height, and a 12 V, 2 A fan/power supply. The image loads from the SmartChemSynth website, so an internet connection is required.

Lux is a human-vision-weighted measurement. It cannot be converted reliably to optical watts or photon flux from wavelength alone. Enter calibrated optical power, or use a validated lux-to-radiant-power calibration for this exact LED and geometry.

Equations used

N photons (mol) = P (W) × t (s) × λ (m) / (h × c × Nₐ)

h = 6.62607015 × 10⁻³⁴ J·s · c = 299,792,458 m/s · Nₐ = 6.02214076 × 10²³ mol⁻¹

Product amount (mol) = product formation rate (g/h) × irradiation time (h) / molecular weight (g/mol)

Apparent QE (%) = product amount / incident photon amount × 100

This is a product-molecule/incident-photon ratio, not necessarily a mechanistic quantum yield. For a rigorous quantum yield, account for absorbed photons and reaction stoichiometry.

Lux readings are shown as recorded and are not used to calculate QE unless a valid radiometric calibration is supplied. The entered optical power should be radiant power reaching the relevant illuminated reactor area, not the LED’s electrical nameplate rating.
