About the Data

Every fixture in GoGobo is scraped directly from manufacturer websites and published spec sheets. We currently cover 12 manufacturers and 500+ fixtures, including both current production models and discontinued units.

We do not accept user-submitted data, and we do not copy from third-party databases. Each manufacturer has a purpose-built scraper that reads their website structure — some use JSON APIs, others require parsing HTML tables, and a few only publish specifications in PDF datasheets.

Each scraper is tailored to a specific manufacturer's website. We extract raw specification values (wattage, weight, dimensions, zoom angles, DMX modes, etc.) and map them to a common schema of 60+ normalised fields. This lets you compare a Martin alongside a Robe alongside a Clay Paky without worrying about how each brand formats their data.

Scrapers run periodically to pick up new products, discontinued models, and spec changes. When a scraper runs, it compares incoming data against existing records and only updates fields that have changed, preserving any manual corrections.

Manufacturers describe the same things differently. One brand lists weight in kilograms, another in pounds. One quotes zoom as "beam angle," another as "field angle." Power might be in watts or volt-amperes. Dimensions might be W×H×D or W×D×H.

GoGobo normalises all values to consistent units: kilograms, millimetres, watts, and degrees. Where a manufacturer provides ambiguous labels, we use the most common interpretation and note any assumptions in our internal quality checks.

Some manufacturers state total lumen output directly. Others only publish lux at a distance or peak candela. When direct lumens aren't available, we estimate total output using the manufacturer's lux or candela measurement combined with the fixture's beam angle.

Estimated values are clearly marked throughout the site with a ~estimated label. These estimates are mathematically derived from the manufacturer's own measurements, but they may differ from a direct lumen measurement due to beam profile, field angle, and optical losses.

Total lumens alone does not indicate perceived brightness on stage — beam angle, optics, and focus all affect how concentrated the light is at any given point. A narrow spot will appear far brighter than a wide wash at the same lumen output.

Each fixture has a quality score (0–100%) representing how many of the key specification fields are populated. A fixture with weight, power, lumens, zoom, pan/tilt, DMX modes, and dimensions all present will score higher than one with only basic specs.

A low score doesn't mean the data is wrong — it means the manufacturer doesn't publish certain specs on their website, or the fixture is a legacy model with limited online documentation. Some older fixtures will always have lower scores because that information simply isn't available.

Each fixture is classified by type (spot, wash, profile, beam, hybrid, FX, fresnel, PC) based on how the manufacturer describes it and its actual feature set. A fixture with framing shutters is a profile; one with gobos but no framing is a spot; one with neither is typically a wash.

"Hybrid" fixtures combine multiple modes — typically beam, spot, and wash — in a single unit. The similar fixtures algorithm accounts for this by considering the fixture's functional role (projection vs wash) alongside its stated type.

The "Similar Fixtures" section on each fixture page uses a weighted scoring algorithm that considers output class, zoom range, weight, power, source type, fixture type, and feature set (framing, gobos, pixel control, strobe, infinite rotation, CRI, tuneable white). Fixtures from different manufacturers are slightly preferred to give you cross-brand alternatives.

Matches below a minimum quality threshold are excluded — if a fixture is truly unique, you'll see fewer suggestions rather than misleading ones.

• We don't independently measure fixtures — all data comes from manufacturer publications
• We don't verify specs against real-world performance
• We don't guarantee accuracy for rigging or electrical planning — always verify against manufacturer documentation
• We don't store or display pricing information
• We don't rank or endorse specific products or brands
