I made a mock-up for adding lighting to our show case with scientific instruments (spot the 90w sox! That's my private property), taxidermied animals and historical media things i found in the building like video tapes and diskettes. It's always been very gloomy because the hallway is not that bright. If you walk past, you cannot look inside due to the glare from other lighting and from outside. I have gotten enough 'Yes, that's good!' reactions, to now start making a full budget estimation.
I am pretty happy with how it looks. 2700k instead of 3000k LEDs would have been nice, but because the hallway light may be converted to 4000k leds at some point, the 3000k you see in this picture will stand out nicely and 2700 will definitely look too yellow. Spot lights would have been most eye catching, but since there is no room inside of the show case to point them at the front of the artifacts, and shining them through the glass would cause tons of glare, i opted for LED strips.
The LEDs used are strips with Epistar SMD2835 ones with a CRI of >90 that can run at a maximum of 40mA a piece, though they will not be running full blast probably. In total, there will be about 16 meters of LED strip in the entire show case totalling close to 160w - one strip of 50cm below each shelf, hidden from view and glare by a piece of angled aluminium. Everything will be dimmable with a random PWM dimmer i have, and the power comes from an old server PSU. The main 12v bus will be inside the closed-off cabinets that the show case is sitting on, with a spur going up to each set of shelves. The extra light is very welcome in the gloomy hallway, currently lit by 1 56w 830 fluorescent per 6 meters i think.
