What is the Best Music Stand Light?

You may wonder what’s your best music stand light. It can be a tough one to answer but we can help you make a choice. Take a look!

Music stand lights are awesome but not everyone makes use of them. Yes, they are usually only used by orchestral musicians who need to light up their sheet music when playing. This device is usually used by these musicians because they always end up playing in dark environments where vision could easily be impaired, making these lights necessary.

As a user of a music stand light, it may be quite some work to decide on the best music stand light. This is due to the variety of options which are available in the market. This guide is meant to help you out in making a choice. We have made a list of what we consider as our favorite options and the different factors to take a look at.

What makes a good Music Stand Light?

What are the factors which you consider when getting a music stand light:

Light Strength: You don’t need a sage to tell you that the main job of a stand light is to help with your visibility by illuminating the area. This makes it very important to consider how bright the light from the stand is. The light shouldn’t only come on for a fair distance but should be capable of lighting up the whole page. As an orchestral musician, it’s important that you can see all parts of the page clearly; including top and bottom.

This means that you have to consider the strength and reach of the light.

Battery-powered or corded: Well, a battery-powered music stand light is considered to be the more preferable choice when picking between these two options. The reason is quite simple. Just imagine how much stress you would have to go through if you had to look for an outlet to plug your stand light each time you wanted to play. The use of batteries makes you good to go at any point in time.

Now, your batteries can run out. So, its available to always have a spare set of batteries in case the ones you’re using run down. It would save you from disaster if it happens in the middle of a show.

LED Vs. Incandescent: Basically, there are two types of bulbs used in music stand lights, namely; Led and Incandescent bulbs. LED bulbs can last considerably longer than incandescent bulbs. However, you may have to pay higher prices for an LED bulb.

But with advancements in technology, LEDs are becoming more common and less costly. They also come with a “warm-up or cool down” time. This means that they’re always ready to be used and will operate at full brightness.

Shields: If you’re trying your best to stay hidden from the audience, you may want to get a light that is shielded from the audience. You don’t want an audience member to be distracted by the glow of your light instead of paying attention to the performers. A light with a bad shield could cause a fair amount of disturbance for the audience.

Material: You must purchase a light that is made from a durable material. Typically, stand lights are made from either plastic, aluminum or steel. Steel is the strongest and most durable of the three, followed by aluminum and then plastic. Steed is the least durable but also the most portable and lightest.
