What this bar does and who buys it
This 42W LED black light bar uses 40 premium LED beads to emit a 385-400 nm wavelength that makes fluorescent paints, posters and uranium glass glow. The 120-degree beam angle and 4200 lumens cover a 24x24ft area, so it suits party hosts, club DJs and classroom demonstrators who need wide UV coverage without the eye-risk of 365 nm tubes.
Who should skip it
Buyers who want a portable battery-powered strip for costumes or a permanent outdoor flood fixture should look elsewhere; this unit requires a US mains plug and its polycarbonate housing is rated for indoor use only. Installers needing a higher-output 50W, 100W, 150W or 200W model for larger venues will also need a different product.
Mounting and common issues
The 180-degree adjustable brackets and included screws with expansion tubes let you fix the 15.1in bar to walls or ceilings in minutes; the 6ft cable with inline on/off switch means no separate dimmer is required. The most frequent problem is forgetting to secure both brackets, which lets the heavy glass face sag and stresses the wedge base connection.

Questions about this item
Does the fixture require a standard US mains outlet to operate?
Yes, the 6 ft cable terminates in a US plug with an on/off switch for direct mains connection.
Will the 120-degree beam angle cover the same area as my older 365 nm tube fixture?
The 385-400 nm LEDs project a 120-degree spread designed to illuminate a 24x24 ft space, which differs from typical tube patterns.
How can I verify the bar is emitting the correct wavelength after installation?
Fluorescent posters, body paint or uranium glass should glow brightly under the 385-400 nm output, confirming proper operation.
