![]() ![]() ![]() With numbers like this, I'm hard-pressed to say that lamp-based projection is anywhere close to going away. More recent projector releases now boast lamp lifespans of 5,000 hours and even a 10,000-hour estimated lifespan if the projector is run in its "Eco" mode, which reduces lamp output for the benefit of longevity. Optoma's new 4K550ST, with 4,500 lumens, and a $3,999 street price, is just one recent example. With solid-state light engines coming on strong in the commercial space, lamp-based models have become an excellent value for situations that demand high brightness on a budget. ![]() This achieved the desired effect, but also increased the ongoing maintenance costs to keep the unit functioning. However, lifespans for much of its history were measured in hundreds of hours it wasn't until the last 10 years or so that we began to see 1000+ hour projection lamps.Īlong with the evolution of the lamps, the need to accomplish higher and higher lumen output led to the introduction of dual-lamp systems. The tried-and-true projection lamp has been around for decades and has consistently undergone new innovations such as brighter light and increased life span. Let's dive into what makes each technology unique, and where you might choose one over the other. However, while LED and laser projectors do offer some significant maintenance and long-term cost benefits, their upfront higher costs can deliver some customers sticker shock, though in the sub-6000 lumen projector market, the prices have now dropped to the point that most will consider a laser projector a more economical choice. With all the hype surrounding new solid-state projection light sources, namely laser and LED, it might seem that the use-case for lamp-based projection is quickly fading away into the annals of history. Most LED projectors max out at around 3,000 - 3,500 lumens. The biggest disadvantage of LED projectors is their brightness. LED projectors are also much quieter than projectors that use traditional lamps. Much faster start up and shut down times as no warm up or cool down is needed. This means that they don’t need as much airflow, allowing them to be quieter and more compact. Since the lamp lasts the life of the projector, you don’t have to worry about buying new lamps.īecause LED’s are so small and only need to semi-conduct, they operate at much lower temperatures. Many LED projectors can run for 10,000 hours or more. LEDs last at least 10 times longer than traditional projector lamps. The biggest advantage of LED projectors is their lamp life and low heat output. When these red, green, and blue LED’s are all combined, they can create an almost exact color match of white light. This light then gets reflected off of a DLP chip or passed through an LCD chip. These LED’s use a low-heat, low-energy process of semiconduction to generate energy, creating an electric signal which gives off a particle of light. ![]() Rather than use a traditional projector bulb, these projectors use a combination of red, green, and blue LED’s. LED projectors are similar to most other projectors. Read on to find out if these projectors are right for you. LED projectors have a significantly smaller footprint than those that use traditional projector lamps. Instead it’s a reference to the light source used.
