Barrina 10W 1FT LED Black Light Bar 4-Pack vs ycponggon 40W LED Black Light Bar

Buy the 4-pack of 1FT bars if you want to spread UV light across a room, a poster wall or a long tapestry, and you want to link several bars from one outlet. Buy the single 40W bar if you want one strong, adjustable fixture for a small room, a stage or body paint. The 4-pack wins on coverage and mounting flexibility; the 40W bar wins on raw output per fixture and a longer cord. Owners of both report the 385-400nm range makes glow paint and posters pop, and neither needs a cooling fan.

• Choose the 4-pack of 1FT bars if you want several small, linkable, magnet-mounted lights to cover a room or a wall of posters.
• Choose the single 40W bar if you want one bright fixture with a long cord and tilting brackets for a small room or stage.
