FLYIN BPH40ST — a 5,400 lm laser DLP projector built for classrooms and meeting rooms that are booked every hour of the day. Fixed-installation design, native 1080p DLP engine, and a 4.5 kg body a single technician can hang. No lamp stock, no lamp schedule, no ladder in the maintenance calendar.
The light source is an MCL laser diode module rated for 20,000 hours in standard mode and 30,000 hours in Eco. There is no lamp to replace. As with every laser projector, output declines gradually with accumulated hours rather than falling off at the end of a rated life — this is stated openly in the specification, and Eco mode is available when you want to stretch the interval further.
The specification carries two figures, and both are published. 5,200 lumens is the ISO/IEC 21118:2020 rating — the average across production units. 5,400 lumens is the centre-of-screen reading, which is how a light meter tends to be pointed. Image uniformity is 85 %, so the corners hold up against the middle instead of falling away. Contrast is 6,000,000 : 1 dynamic, full on / full off — a dynamic figure, stated as such, because that is what the measurement is.
Native resolution is 1920 * 1080, with 1.07 billion colours and a 16 : 9 frame that also accepts 4 : 3 and 16 : 10 content. Two HDMI 2.0 inputs take signals up to 3840 * 2160 at 60 Hz with HDCP 1.4 / 2.2 support, so a 4K laptop or media player connects without a scaler in between. The panel is 1080p; the inputs are 4K-capable. Both statements are true at once and are kept separate here.
Vertical and horizontal keystone each travel ±30°, and four-corner correction then pulls each corner independently — for a wall that leans, a screen that is not level, or a mount that had to go where the ceiling allowed. Screen size runs 40" to 300" on the diagonal with a 1.16 lens offset and manual focus. The unit installs at 360°, horizontally or vertically, in front, rear, ceiling-front or ceiling-rear orientation, and a security lock slot is provided.
Two HDMI 2.0 inputs for the laptop, the streaming stick, and the presenter who brought a second one. A VGA D-sub 15 input for the room PC nobody has replaced. Audio in and out on 3.5 mm jacks, a 16 W speaker for rooms without a sound system, and a USB-A port rated 5 V / 1.5 A that powers a stick or a dongle. RS232, RJ45 and Mini USB (DFU) handle control and firmware, so the unit fits an existing AV rack rather than sitting beside it.
Switched on by the room, not by a person. Connect AC and the projector starts; a signal on the input starts it too. Auto signal search and auto PC adjustment take the picture the rest of the way, with auto vertical keystone as the unit settles. When the source disappears, ECO mode engages, a five-minute sleep follows by default, and a timer can shut the unit down at the end of the day. Six display presets are available — Standard (cool / warm), Eye-care, Vivid, DICOM, sRGB and User — alongside HSV colour management, five menu positions, keypad lock, power-on password, built-in test patterns and Active 3D support.
DICOM here is a display preset, not a medical certification or a diagnostic claim.
210 W consumption, below 0.5 W in standby, and ≤ 35 dB in standard mode / < 32 dB in Eco. The body measures 337 * 295 * 113 mm and weighs 4.5 kg net, 5.5 kg gross. Operating range is 0–40 °C at 20–80 % relative humidity, non-condensing, up to 3,000 m altitude, with a dedicated high-altitude mode above 1,700 m. In that mode the ambient ceiling becomes 0–35 °C; above 35 °C the light source is throttled and fan noise rises. Both limits come from the manufacturer's own notes and are worth knowing before a summer installation.
5,200 lumens and a 1080p panel are honest numbers — and they have a ceiling.
