Bobrick B-164 2436 Bobrick Led Backlit Mirror

The B-164 2436 is 24 inches wide by 36 inches high (610 x 914mm). The same LED backlit mirror is built in three other sizes: B-164 1830 at 18 x 30 inches (460 x 762mm), B-164 2442 at 24 x 42 inches (610 x 1067mm), and B-164 2739 at 27 x 39 inches (686 x 990mm). If you are laying out a restroom around a fixed mirror band, the 24 inch width gives you two height choices, 36 and 42 inches, on the same footprint.

It is built for hardwired wall installation, but Bobrick offers a 30 inch cord with a three-prong plug as a separate item, ordered as 164-57. If there is no junction box behind the mirror location and you have a GFCI receptacle you can reach, add the cord kit to the order. On new construction or a gut remodel, hardwire it and skip the cord.

Bobrick lists the B-164 as ADA compliant. Compliance for a mirror is set by mounting height, so the rating holds only if you install it to the required reflecting-surface height for the fixture it serves, which is a field decision, not something the mirror carries out of the carton. The 24 x 36 inch glass gives you enough vertical run to land the bottom edge at an accessible height and still leave usable reflection for a standing user.

The glass is 6mm safety film backed, bonded to an aluminum frame on the back side, and that frame has key lock holes for wall mounting. Key lock holes mean the unit drops onto fasteners already set in the wall and then locks down, so it cannot be lifted straight off the wall the way a hook-hung mirror can. That is what you want in a public restroom or a school. Plan your anchors for the wall type you actually have, since the mirror ships with the frame and the hole pattern, not with the substrate anchors for every wall.

At the 24 x 36 inch size it draws 24 watts and puts out 2640 lumens at 3000K. The other sizes scale with the glass: 19W / 2100 lumens on the 18 x 30, and 26W / 2900 lumens on both the 24 x 42 and the 27 x 39. All four are 3000K, so a mix of sizes in the same restroom will read the same warm white, which matters if you are standardizing across a floor or a portfolio.

The B-164 is built for commercial duty, not residential: the mirror and mounting panel carry an IP44 rating, the silver backing is lead free and exceeds ISO 9227:201 120 hour corrosion testing, and the light engine is separately rated IP66 with an estimated 50,000 hour life. That is the combination that survives a public washroom, where splash and cleaning chemistry kill consumer mirrors at the edges first. Where a backlit unit stops making sense is a restroom that already has compliant vanity lighting and where you want the cheapest replaceable mirror on the wall, since a plain framed mirror has no electrical rough-in and nothing to fail. If the goal is to delete a separate light fixture and its wiring from the wall above the lav, the backlit unit does both jobs on one connection.

The 6mm glass is safety film backed, so a break stays bonded to the film and the frame rather than dropping shards into the lavatory. That is the reason this style goes into schools, healthcare and hospitality washrooms where a plain plate mirror is a liability. Worth knowing before you spec it: the film backs the glass, it does not make the mirror impact resistant, so in a genuinely abuse-prone location a stainless or laminate-clad mirror is the tougher call.

Width is identical at 24 inches; the difference is 6 inches of height, 36 versus 42, and slightly more output. The 2436 is 24W and 2640 lumens, the 2442 is 26W and 2900 lumens, both at 3000K. Pick on the wall space above the lavatory and on where your accessible mounting height puts the bottom edge. Where you have the vertical room, the 2442 buys more reflection and a bit more light for the same footprint on the wall.

The light engine is IP66 rated and the mirror and mounting panel are IP44. IP66 covers dust-tight and water jets, which is why this survives a washroom that gets hosed or pressure-cleaned. The lead free silver backing is also tested past ISO 9227:201 at 120 hours of corrosion exposure, which is the failure mode that shows up as black creep at the mirror edge after a year in a wet room. Estimated life on the light engine is 50,000 hours.

Flat lighted is the style: a flat glass face with the LED illumination in the panel and no decorative front frame. The only frame is aluminum and it sits behind the glass to carry the mounting holes. So the visible result on the wall is glass and light, which is what most commercial restroom drawings are calling for when they show a lighted mirror.
