OmniCure S1500 vs SunSpot 2
The OmniCure S1500 and Uvitron SunSpot 2 are both 200 W mercury short-arc spot curing systems, so this is not an arc-versus-LED decision; the core light-source technology is the same. The real differences are spectral output and intensity control (the S1500 ships band-pass filtered to 320-500 nm and drives up to 23 W/cm2 with fine 1% iris control plus RS-232/PLC automation, while the SunSpot 2 runs 275-650 nm broadband at over 18 W/cm2 UVA), together with commercial availability: the SunSpot 2 is current-production with a public $4,220 price and US stock, whereas the base S1500 has been discontinued in favor of the S1500 Pro. Match the system to your adhesive's cure band and your automation and budget needs rather than to a headline intensity number, since the two are measured over different spectral windows.
OmniCure S1500 vs SunSpot 2, side by side
| Spec | OmniCure S1500 | SunSpot 2 (ours) |
|---|---|---|
| Light source | 200 W mercury short-arc ("Intelli-Lamp"), pre-aligned; typical lamp life up to 4,000 h with a 2,000 h strike guarantee | 200 W mercury short-arc lamp |
| Output spectrum | 320-500 nm with the standard band-pass filter; broadband mercury source, with unfiltered and alternate-filter options | 275-650 nm broadband (UVB/UVC through visible) |
| Peak intensity | Up to 23 W/cm2 (23,000 mW/cm2) at 320-500 nm with the standard filter; up to 27.7 W/cm2 unfiltered | Over 18,000 mW/cm2 (18 W/cm2) UVA |
| Outputs / heads | Single light-guide output | Single guide, up to 4 poles via liquid light-guide splitter |
| Control and automation | Rotary iris in 1% increments, shutter, exposure timer, lamp-hour meter; optically isolated RS-232, PLC I/O and foot pedal | Integral electronic timer and shutter, foot pedal |
| Price (USD, as of 2026-07-18) | No public list price; sold by quotation or distributor | $4,220 (UV1853 120 VAC / UV2132 240 VAC) |
| Availability and warranty | Base S1500 discontinued, replaced by the S1500 Pro (as of 2026-07-18); base units mostly on the used market | In production, US stock, ships 24-48 hrs; 2-year OEM warranty |
If you need the highest peak irradiance from a 200 W arc system, the S1500 leads: up to 23 W/cm2 across 320-500 nm with the standard filter and up to 27.7 W/cm2 unfiltered, measured over a broad spectral window. Its rotary iris adjusts intensity in fine 1% increments, and paired with the shutter and exposure timer that makes it well suited to high-throughput, repeatable adhesive bonding. It also has the richer automation story: optically isolated RS-232, PLC I/O and a foot-pedal input for tight integration into production and dispensing lines, plus interchangeable band-pass filters to tune the output to your adhesive chemistry and a pre-aligned long-life Intelli-Lamp that needs no manual alignment. It is backed by Excelitas/OmniCure's established global distribution and service network. One caveat for new buyers: the base S1500 has been discontinued in favor of the S1500 Pro, so a current purchase is usually the Pro variant. If programmable RS-232/PLC control is your priority on the Uvitron side, our SkyBeam LED system is a closer match than the SunSpot 2.
- Very high UV irradiance for a 200 W spot system: up to 23 W/cm2 at 320-500 nm with the standard filter, and up to 27.7 W/cm2 unfiltered
- Fine, repeatable intensity control from a rotary iris adjustable in 1% increments, paired with a shutter and exposure timer for high-throughput adhesive bonding
- Pre-aligned, long-life Intelli-Lamp: typical UV lamp life up to 4,000 hours with a minimum 2,000-hour strike guarantee and no manual lamp alignment
- Strong automation interfaces: optically isolated RS-232, PLC I/O, and foot-pedal inputs for integration into production and dispensing lines
- Interchangeable band-pass filters let users tailor the output band to the adhesive chemistry
- Backed by an established global manufacturer (Excelitas/OmniCure) with broad distributor and service coverage
The SunSpot 2 fits when broadband output, transparent pricing and fast US availability matter. Its 275-650 nm spectrum reaches shorter UVB/UVC as well as visible wavelengths, which can be the deciding factor if your adhesive or resin chemistry needs energy below the S1500's standard 320-500 nm band-pass window. It lists at a public $4,220 (UV1853 for 120 VAC, UV2132 for 240 VAC), ships from US stock in 24-48 hours and carries a 2-year OEM warranty, versus quote-only pricing and a largely used-market situation on the base S1500. For multi-point work, a single SunSpot 2 splits to as many as 4 poles through a liquid light-guide splitter, so you can cure several locations from one system without stepping up to a higher-tier unit. Its integral electronic timer, shutter and foot pedal cover manual and semi-automated cells cleanly. Because both systems share the same 200 W mercury short-arc source, cure behavior is broadly comparable, but validate on your actual adhesive before switching, since the two are filtered and measured differently.
- Mercury arc source requires lamp warm-up and periodic lamp replacement (finite 2,000 to 4,000 hour lamp life), unlike an instant on/off LED source
- Single light-guide output on the S1500; simultaneous multi-point curing requires external light-guide splitting or a higher-tier system
- The original S1500 has been discontinued and replaced by the S1500 Pro (as of 2026-07-18), so new purchases are typically the Pro variant and base S1500 units are mostly found on the used market
- No publicly listed price; sold via quotation or distributor, which makes direct price comparison harder
- Standard configuration is band-pass filtered to 320-500 nm (UVA-centered); broader or UVC-inclusive output requires the unfiltered or an alternate-filter option
Questions
Is the SunSpot 2 a drop-in replacement for the OmniCure S1500?
Not a literal drop-in. Both are 200 W mercury short-arc spot systems that fill the same role with a flexible light guide, but light-guide fittings, mounting and control I/O differ, and the S1500's standard output is filtered to 320-500 nm while the SunSpot 2 runs 275-650 nm broadband. Confirm light-guide coupling and validate cure on your adhesive before treating it as a swap.
Will the SunSpot 2 cure my adhesive exactly like the S1500?
We cannot guarantee identical cure without testing. Both use a 200 W mercury arc source, but the S1500 standard configuration is band-pass filtered to 320-500 nm, the SunSpot 2 is 275-650 nm broadband, and their peak intensities are quoted over different spectral bands (23 W/cm2 at 320-500 nm versus over 18 W/cm2 UVA). Always run a sample cure and process validation first.
What does the SunSpot 2 cost, and how fast can I get one?
The SunSpot 2 lists at $4,220 (UV1853 for 120 VAC, UV2132 for 240 VAC), ships from US stock in 24-48 hours and includes a 2-year OEM warranty. The S1500 has no public list price and is sold by quotation, and the base model has been discontinued in favor of the S1500 Pro as of 2026-07-18.
