Here's the comparison. Note that each model appears in the catalog in two variants (mono and color — GT1930/GT1930C and GT1930L EF/GT1930LC EF), but all variants within a model share the same specs for the three attributes you asked about.
| Attribute | Prosilica GT 1930 | Prosilica GT 1930L |
|---|---|---|
| Operating temperature | –20 °C to 65 °C | –30 °C to 70 °C (housing temperature limit) |
| Weight | 211 g | 372 g |
| Max power consumption | 3.5 W | 3.88 W |
Summary of differences:
- Temperature: The GT 1930L has a wider operating range — it runs 10 °C colder at the low end (–30 °C vs –20 °C) and 5 °C hotter at the high end (70 °C vs 65 °C). Note the GT 1930L's range is specified as a housing temperature limit. alliedvisi... +1alliedvision.com ↗“thermal.max_operating_temp_c=65 °C, thermal.min_operating_temp_c=-20 °C”alliedvision.com ↗“thermal.max_operating_temp_c=70 °C, thermal.min_operating_temp_c=-30 °C, thermal.operating_temp_condition=Housing temperature limit”
- Weight: The GT 1930L is heavier at 372 g versus 211 g — about 76% more. alliedvisi... +1alliedvision.com ↗“mechanical.weight_g=211 g”alliedvision.com ↗“mechanical.weight_g=372 g”
- Power draw: The GT 1930L draws slightly more at 3.88 W maximum versus 3.5 W for the GT 1930. Both models otherwise share the same core imaging platform: Sony IMX174 global-shutter sensor, 1936 × 1216 resolution, GigE (1000BASE-T / PoE) interface, and 7–25 VDC AUX or 802.3at Type 1 PoE power input. alliedvisi... +1alliedvision.com ↗“power.max_power_consumption_w=3.5 W”alliedvision.com ↗“power.max_power_consumption_w=3.88 W”
