Spectra Vantage overlaps with the Black Series on UST-specific ALR purpose and a 150-inch product listing, but it publishes a slightly lower 0.5 gain compared with NothingProjector's 0.6.

What the gain difference means
A 0.5-gain surface is more conservative with peak brightness than a 0.6-gain surface, all else equal. But “all else equal” rarely applies across different ALR materials. Screen structure, viewing distribution and room-light direction matter at least as much as the decimal point.
A data inconsistency worth noticing
The Spectra 150-inch product listing offers a 150-inch custom configuration, while a material-properties table on the same retailer site has historically shown a smaller maximum size for the base Vantage UST 0.5 surface. That is exactly why large custom sizes should be verified at the point of purchase rather than assumed from a generic material table.
The Black Series merchant page is more explicit about its 150-inch construction tradeoff: screens over 120 inches use a splicing process and may show a fine seam.
