Comparisons

A side-by-side comparison of EB and OSRAM H11 LEDr lamps, covering packaging, construction, emitting geometry, beam patterns, illuminance, temperature and noise. EB has smaller, lighter packaging, a thinner emitting structure, higher right-side and peak illuminance, and lower surface temperature. OSRAM records slightly lower B50L illuminance, higher centre-left readings and lower fan noise.

A side-by-side comparison of EB and Philips H11 LEDr lamps, covering construction, emitting geometry, Box-system images, beam patterns, illuminance, temperature and noise. EB records a thinner emitting structure, higher right-side illuminance, and lower surface temperature and fan noise. Philips records slightly lower B50L illuminance, while peak illuminance is nearly identical.

A side-by-side comparison of EB and Luxfighter H11 LEDr lamps covering packaging, construction, emitting geometry, beam patterns, illuminance, temperature and noise. EB offers a smaller package, a metal retaining spring and thinner dual-sided emitting geometry. It also records higher right-side and peak illuminance, slightly lower B50L illuminance and a lower surface temperature after 30 minutes. Luxfighter has a lighter empty package, higher centre-left illuminance and lower fan noise.

This side-by-side comparison examines EB and E4E H11 LEDr lamps across packaging, mounting structure, emitting geometry, beam distribution, illuminance, temperature and fan noise. EB records thinner opposing-surface geometry, higher EMAX and right-side readings, and lower temperature and noise. E4E records the lower B50L value and uses smaller, lighter packaging, although the tested box has no hanging slot and the lamp uses a universal base without a separate metal retaining spring.

What should be checked before selecting an H11 LEDr product for a bulk order? This five-product comparison examines packaging, mounting components and emitting geometry alongside beam distribution, temperature and fan noise, showing differences that matter beyond a headline brightness figure.

The compliance difference in an LEDr vs LED retrofit comparison starts with the approval route, not the lighting technology. An LED replacement light source, commonly shortened to LEDr, can follow UN Regulation No. 37 only when its specific category and type are covered by the applicable requirements. A product sold as an LED retrofit is a market description, not proof of UN R37 type approval. An LED substitute follows a different regulatory concept and should not be treated as another name for LEDr. Importers should compare the approval document, category marking, product type and permitted application before discussing price or fitment.

The H11 vs H7 vs H4 LEDr question is not a choice between three equally approved products. As of 15 July 2026, H11 is an established UN R37 LED replacement light source category, and a March 2026 amendment added H8, H16 and HB4. H7 and H4 are not established categories. They sit on the working agenda as under investigation, and some countries cover selected H7 and H4 products through vehicle positive lists, which is a separate mechanism with a narrower scope.

UN R37 covers approved LED replacement light sources (LEDr), R128 covers LED light sources for new lamp applications, and R99 covers gas-discharge sources. Compare their approval scope, E-mark meaning and buyer checks to identify the right regulatory route for each product.
