OmniCure S2000 vs SunSpot 2
The OmniCure S2000 and the Uvitron SunSpot 2 are both 200 W mercury short-arc spot UV curing systems, so this is not an arc-versus-LED decision. The meaningful differences are in spectrum and control philosophy: the S2000 runs a filtered, application-tunable output with closed-loop irradiance feedback aimed at validated production, while the SunSpot 2 delivers higher raw UVA through a full unfiltered 275-650 nm broadband spectrum at a published price with US stock. Note that Excelitas has since introduced the next-generation S2000 Elite, so a buyer seeking a new unit may be directed there rather than to the original S2000.
OmniCure S2000 vs SunSpot 2, side by side
| Spec | OmniCure S2000 | SunSpot 2 (ours) |
|---|---|---|
| Source type | 200 W mercury short-arc lamp (OmniCure Intelli-Lamp), which tracks lamp hours of use | 200 W mercury short-arc lamp |
| Spectrum / wavelengths | Filtered broadband; standard 320-500 nm bandpass filter, with optional 250-450, 320-390, 365, and 400-500 nm filters selectable at purchase | 275-650 nm broadband, unfiltered (UVB/UVC through visible) |
| Peak intensity | Up to about 10 W/cm2 UVA at the light-guide tip, depending on filter and light-guide configuration | Over 18 W/cm2 (18,000 mW/cm2) UVA |
| Channels / multi-site | Single front-panel light-guide port; multiple sites fed by passive multi-leg fiber light guides that split the single source | Single guide; up to 4 poles via liquid light-guide splitter |
| Control | Integral exposure timer, supplied foot pedal, RS-232 and optically isolated PLC/alarm I/O, plus closed-loop feedback (optical UV sensor and motorized iris) holding output within about +/-5% of setpoint | Integral electronic timer and shutter, foot pedal |
| Price (USD) | Quote-based; no public manufacturer list price (secondary-market refurbished units listed near $3,450, not an official new-unit price) | $4,220 |
| Warranty / availability | See manufacturer datasheet | 2-year OEM warranty, US stock, ships in 24-48 hours |
Choose the OmniCure S2000 when process repeatability and automation integration matter more than raw output. Its closed-loop feedback, an optical UV sensor paired with a motorized iris, actively holds irradiance within about +/-5% of setpoint as the lamp ages, which is a genuine advantage for validated, high-mix production where drift must be controlled and documented. The RS-232 serial link and optically isolated PLC/alarm I/O, plus the supplied foot pedal, make it straightforward to drop into an automated line with proper handshaking, and the Intelli-Lamp's automatic tracking of lamp hours simplifies maintenance scheduling. If your application needs a specific spectral band, for example 365 nm to match a photoinitiator or 400-500 nm to reduce UV exposure, the selectable bandpass filters let you tune the output at purchase. For a regulated or highly automated process that depends on stable, feedback-controlled irradiance, the S2000 is purpose-built for that role.
- Real-time closed-loop feedback (optical UV sensor plus motorized iris) actively holds irradiance within about +/-5% of setpoint, a genuine advantage for repeatable, validated production processes
- Intelli-Lamp automatically tracks lamp hours of use, simplifying maintenance scheduling
- Application-tunable spectral output with multiple selectable bandpass filter options (for example 320-500 nm standard, 365 nm, 400-500 nm)
- RS-232 serial and optically isolated PLC/alarm I/O plus a supplied foot pedal make it straightforward to integrate into automated lines
- Solid UVA output (up to about 10 W/cm2 UVA at the light-guide tip) suits fast cures and broad adhesive compatibility
- One source can cure several sites at once via multi-leg fiber light guides
- Well-established, widely supported platform with a long guaranteed lamp life (2000 hr guaranteed, maximum service life reported up to about 4000 hr)
Choose the SunSpot 2 when you want more raw UVA, a full unfiltered spectrum, and transparent pricing and availability. It delivers over 18 W/cm2 UVA at the guide tip versus about 10 W/cm2 on the S2000, and its 275-650 nm broadband output (UVB/UVC through visible, no bandpass filter) gives broad photoinitiator compatibility and fast cures without pre-selecting a spectral window. Control is deliberately simple: an integral electronic timer and shutter with a foot pedal, well suited to R&D, job shops, and production cells that do not need a closed feedback loop or PLC handshaking. It is a published $4,220 (UV1853 for 120 VAC, UV2132 for 240 VAC), carries a 2-year OEM warranty, and ships from US stock in 24-48 hours, so lead time and total cost are known up front rather than quote-dependent. If you value higher intensity, full-spectrum flexibility, and fast, predictable procurement over closed-loop automation, the SunSpot 2 is the stronger fit.
- The original S2000 has been superseded by the next-generation OmniCure S2000 Elite; a buyer seeking a new unit would likely be directed to the Elite, though existing S2000 support reportedly continues.
- As a mercury short-arc system it requires lamp warm-up and periodic lamp replacement (2000 hr guaranteed), and does not offer the instant full-power on/off of LED systems.
- No manufacturer list price is publicly published; pricing is quote-based. Only secondary-market resale listings were visible (for example a refurbished unit listed near 3,450 USD), which is not an official new-unit price.
- Multi-site curing relies on passive multi-leg light guides that split and therefore divide the single source output, rather than independently powered and independently timed channels.
- 3 mm single-leg liquid light guides are not compatible with the S2000.
Questions
Is the SunSpot 2 a drop-in replacement for the OmniCure S2000?
Not a literal drop-in, though the workflow is similar. Both are 200 W mercury short-arc systems that cure through a light guide, support single-guide-plus-splitter multi-site curing, and use timed, foot-pedal-actuated exposure. However, the SunSpot 2 does not replicate the S2000's closed-loop irradiance feedback or its RS-232 and PLC automation I/O, and light-guide fittings and filter options differ. Validate your cure and any integration before switching.
Will the SunSpot 2 cure my adhesive exactly like the S2000?
We cannot guarantee an identical cure. The SunSpot 2 runs a full unfiltered 275-650 nm spectrum at over 18 W/cm2 UVA, which differs from a filtered S2000 output, so exposure time and spectral match should be verified against your photoinitiator. Uvitron can advise, but you should run a bench qualification before committing a production process.
What does the SunSpot 2 cost and how fast can I get one?
It is $4,220 (UV1853 for 120 VAC or UV2132 for 240 VAC), with a 2-year OEM warranty, held in US stock and typically shipping in 24-48 hours. The S2000 is quote-based with no public list price; only secondary-market refurbished listings (around $3,450) were visible, which are not official new-unit pricing.
