L2D2灯泡(氘灯) from Germany Dinghao has the longest life, the highest light output and the best stability. Its ceramic structure ensures a uniform and optimum temperature distribution, which are the most important factors for stable operation. The L2-4000 series lamps assure an operating life of 4000 hours-4 times longer than conventional lamps. This is the longest operat- ing life of any deuterium lamp. The L2-2000 series lamps produce 1.3 times higher light output than conven- tional lamps. The L2-4000 series lamps even offer light output 1.1 times higher than conventional lamps.
The L2D2 series deuterium lamps from Hamamatsu feature a ceramic electrode structure that delivers long operating life (up to 4000 h for the L2‑4000 series) and high stability, with output fluctuation of only 0.05 % p‑p and drift of ±0.3 %/h. Light output is 1.3 times higher for the L2‑2000 series and up to 14 times higher for the L2‑4000 series compared with conventional lamps.
These lamps are intended for analytical instruments such as UV‑VIS spectrophotometers, HPLC, capillary electrophoresis, atomic absorption spectrophotometers, SOx/NOx analyzers, film‑thickness measurement devices, and thin‑layer chromatography.
