Halloween projector: LED lights or a video projector?
Published October 9, 2026
Short answer. If you want a ghost or a bat on a nearby wall tonight, with no phone and almost no setup, a cheap LED projector light is enough. If you want the picture to fit a window, a door or a pumpkin, to move properly, or to be your own video, you need a video projector with an HDMI input and a phone or laptop to feed it. Both are sold as a “Halloween projector”. They are different gadgets.
Search for a Halloween projector and the results mix two things that have almost nothing in common. One is a cheap, simple lamp. The other is a real projector. It is easy to buy the wrong one, so here is how to tell them apart.
The two kinds
LED projector lights. A small lamp, often on a stake you push into the lawn or a plug-in that sits on a shelf. Inside is an LED and a slide, a film strip or a spinning disc. It throws a ghost, a bat or a pumpkin onto the wall, and the image is fixed or turns slowly. You plug it in, point it and you are done. Some boxes play a few built-in animations instead. They sit between the two kinds: more motion than a lamp, but the clips are fixed.
Video projectors. The kind used for movies and presentations. It has an HDMI input and shows whatever you connect: a phone, a laptop, a streaming stick. For Halloween you feed it a looping effect.
| LED projector light | Video projector with a phone | |
|---|---|---|
| What it shows | A few fixed images, maybe turning | Anything: effects, your own photos and videos |
| Fits a window, a door, a pumpkin | No. It throws a circle or a rectangle. | Yes. You drag the corners of a shape onto the object. |
| Setup | Push the stake in, plug in, aim | Place it, connect the phone, fit the picture |
| Brightness | Low. Works within a few meters, in the dark. | Your choice, from about 300 to 4,000 ANSI lumens and up |
| Next year, or Christmas | The same images | New effects, other seasons, your own content |
| Cost | The cheapest option by far | A projector (about $150 for a basic one), an adapter and a cable |
When the cheap light is the right buy
It often is. If you want a few ghosts on the side of the garage for the kids, you do not want to carry gear, and you do not mind the same picture every night, buy the light and be happy. It takes a minute to set up and it survives a bit of rain if the box says so.
It also suits a rental, where you cannot hang anything, or a yard full of small decorations where each one needs its own spot of light.
When it is not enough
- You want the picture to land on a window frame, a door or a pumpkin and stop at the edge. A lamp lights a circle, whatever is in it.
- You want real motion: a figure that walks past the window, bats crossing a moon.
- You want your own video or photo.
- The surface is big. A garage door or a house front needs far more light than any stake lamp gives. The garage door guide has the numbers.
- You want to use the same gear for Christmas, a birthday or movie night.
What to check on an LED projector light
- An outdoor rating. Look for IP44 or better on the box, and IP65 if it will sit in the rain. No rating, keep it dry.
- Focus. A focus ring beats a fixed lens, because you will not stand exactly where the maker assumed.
- How many images. Discs and slides vary. See whether the ones you want are in the box.
- Power. Mains is steadier than batteries, and batteries on a cold night give up early.
- A timer. Saves you walking out to switch it off.
- A brightness figure. Most listings do not give one in ANSI lumens. Treat any other number with suspicion.
What a video projector adds
It lets you fit the picture to the thing. Dragging four corners bends the picture so it covers a door and only the door. A circle fits a pumpkin. You can run a different effect on each surface at once: a ghost in the window, a face on the pumpkin, bats over the garage.
Bengala does this from an iPhone or iPad. You connect the projector with a USB-C or Lightning to HDMI adapter, or with AirPlay, and drag a shape onto the object. It does not work with the lamp type, because those have no input to send a picture to. It needs a projector or a TV with HDMI or AirPlay.
The free plan gives you one project, with as many shapes as you like, and a few free effects, two of them for Halloween. A small Bengala watermark drifts across the picture, and Pro removes it. Pro also unlocks every effect.
If you already own a video projector, you probably have all you need. If you do not, read the cheap projector guide before you buy one, because the brightness numbers on cheap listings are often not ANSI lumens. The recommended gear page has a few picks.

Questions
What is a Halloween projector?
Two different things go by that name. One is a small LED lamp that throws a fixed Halloween image on a wall. The other is a normal video projector playing Halloween content. The first is cheap and simple. The second is flexible and takes some setup.
Do I need a special projector for Halloween?
No. Any video projector with an HDMI input works. What makes it Halloween is the content you send to it.
Are Halloween projector lights bright enough for a house?
For a nearby wall in the dark, yes. For a garage door or a house front, no. Those need a video projector rated at 1,000 ANSI lumens or more, and more again for a large front or near a streetlight.
Can my phone be the projector?
No. A phone screen gives off light but does not throw a picture onto a wall. You connect the phone to a projector, and the projector does the throwing. A few phones had a tiny projector built in. They are dim and rare.
Can I use a TV instead?
A TV shows the picture on its own screen. That can be good for a window display indoors, but it is not projection onto a surface.
Is it free to try Bengala?
Yes. You can start with the free plan and one project, and you do not need an account.
