Models and specifications
Values are taken from the Light Sources datasheet. For a specification not listed here, ask an applications engineer.
| Model | Range (nm) | Connector | Lamp | Lifetime (h) |
|---|---|---|---|---|
| LS-BA 1 | 350–2500 | — | Balance (5 V halogen lamp plus blue LEDs) | 10000 |
| LS-HA 2 | 400–2500 | — | Halogen | 10000 |
| LS-DH-4 3 | 185–2500 | SMA905 | Deuterium-Halogen (D2 + HAL) | — |
| LS-D2 4 | 185–400 | SMA905 | Deuterium | 1500 |
| LS-WB | 400–1000 | — | Wideband | 30000 |
- LS-BA: AC input 100–240 VAC. Control: potentiometer, or on/off from SpectraSmart or the SDK.
- LS-HA: Stability 0.5%; drift <0.3% per hour; warm-up 30 minutes.
- LS-DH-4: Deuterium lamp 185–400 nm, life >1,000 hours; halogen lamp 400–2500 nm, life >2,000 hours. Stability 0.15%; drift <0.25% per hour; warm-up 30 s. AC input 100–240 VAC. Control: manual, SpectraSmart, SDK or GPIO. SMA905 fiber coupling.
- LS-D2: Lamp life 1,500 hours at 230 nm. Drift <±0.25%; warm-up 15 minutes. Control: manual, GPIO, SpectraSmart or SDK; PWM. SMA905 fiber coupling.
A dash means the value is not specified for that model. An applications engineer can help with any specification not listed.

Discuss the Light Sources with an engineer
Send the sample type, the wavelength range and the accuracy required. An Evolve Sensing engineer will confirm the configuration, or recommend a different instrument where one suits the measurement better.
