Each resin lamp is checked by hand before it leaves the workshop. Most issues have simple explanations.

You ordered a handcrafted resin lamp. It arrived, you plugged it in, and something seems off. Maybe it's flickering. Maybe it's dimmer than you expected. Maybe the resin has a small bubble or a surface mark that wasn't in the photos. Before you assume something is wrong, read this guide. Most reported issues with resin lamps fall into one of three categories: expected behavior, simple fixes, or cosmetic variations that are part of the handcrafted nature of the piece.

This guide covers every common problem we've seen, what causes it, and what to do. If your specific issue isn't covered here, the final section explains how to reach out for support.

Is the Flickering Normal? Understanding Resin Lamp LED Behavior

The most common concern from new resin lamp owners is flickering. The good news is that most flickering has a simple, non-defect cause.

Resin lamps use USB-powered LED modules. When you plug the lamp into a USB port that is cycling power (for example, a PC port that enters power-saving mode when the computer is idle, or a USB hub that manages power across multiple devices), the LED may flicker briefly as the voltage fluctuates. This is not a lamp defect. It's a power-source behavior.

A loose or under-powered USB connection is the most common source of flickering, and the easiest fix.

First Steps When You See Flickering

  • Try a different USB port: Move from the PC's front panel USB to a rear port, which is more stable on most systems.
  • Try a wall adapter: Plug the USB cable into a standard 5V wall charger. Wall adapters provide more stable, consistent power than PC USB ports.
  • Check the cable connection: Unplug and firmly re-seat the USB cable on both ends. A partial connection causes inconsistent power delivery.
  • Test the inline switch: Toggle the switch on and off a few times. A switch that's partially toggled can cause intermittent contact.

If flickering persists after trying all four of the above steps, that suggests a genuine LED module issue rather than a power source problem. In that case, contact support directly (see the final section).

The Lamp Is Dimmer Than Expected

Resin lamps are ambient accent lights, not task lights. If you're expecting a lamp that can illuminate a room for reading or working, resin lamps are not designed for that purpose. The warm LED inside provides a decorative glow: enough to see the resin piece clearly and create a soft pool of warm light around it on your desk or shelf. It is not meant to compete with a bedside reading lamp or a desk work light.

That said, there are cases where dimness indicates a problem:

Symptom Likely Cause Action
Soft ambient glow, visible in dark room Normal lamp behavior No action needed
Barely visible even in a dark room Low-power USB port or failing LED Try wall adapter; contact support if persists
Much dimmer than when first plugged in LED degradation over months/years Normal wear; contact support for replacement
Dim only on one side of the resin Directional LED placement (intentional) Rotate the lamp for better glow distribution

One thing worth noting: some lamps look significantly brighter in a dark room than in daylight. This is expected behavior. Resin lamps are designed as evening and nighttime accent pieces. If you're evaluating the glow in a brightly lit room during the day, it will look underwhelming compared to how it performs at night.

Bubbles, Clouding, and Surface Variations

Resin bubbles are the most common cosmetic "defect" reported, and in most cases they are not defects at all. They are a natural byproduct of the handcrafting process.

When liquid resin is poured into a mold, small amounts of air become trapped. Professional resin artisans use techniques to minimize this, including heating the resin to reduce viscosity, using pressure chambers during curing, and sanding and polishing the surface after curing. However, some micro-bubbles remain in every handcrafted piece. If you look closely enough, you will find them.

What distinguishes a cosmetic bubble from a structural defect:

  • Cosmetic: Small bubbles visible only under close inspection, not affecting the structural integrity or the glow of the piece
  • Cosmetic: Surface micro-scratches from the polishing process
  • Cosmetic: Slight variation in resin density creating different glow patterns at different angles
  • Potential issue: A large void or crack that affects the structural integrity of the block
  • Potential issue: A bubble directly in front of the main figure that obscures the design

For more on why every handcrafted resin piece is slightly different, our post on why no two resin lamps are identical covers the science of handcraft variation in depth.

The Lamp Glows Unevenly or Only on One Side

Some customers notice that the resin glow is stronger on one side of the piece than the other. In most cases this is intentional, not a defect.

The LED module is positioned at the base of the lamp and directs light upward and slightly forward toward the main figure embedded in the resin. This creates a concentrated glow in the area of the figure and softer illumination toward the edges and back of the block. Rotating the lamp 90-180 degrees on your desk can change the lighting character significantly. Some orientations will appear brighter, others will show more of the depth and interior detail of the resin.

If you've tried multiple orientations and one area of the resin is completely dark regardless of position, that may indicate an LED module positioning issue. In that case, contact support.

The Cable or Switch Feels Loose

Inline switches and USB cables experience wear with repeated use. If your switch feels loose or doesn't click firmly, the internal contact may have shifted. This is fixable:

  • Check that the switch is fully toggled (not in a halfway position)
  • If the switch housing is loose, try gently pressing it back into the cable housing
  • If the lamp works when the switch is held in a specific position but not normally, the switch mechanism has failed and needs replacement. Contact support for a replacement cable.

How to Care for Your Lamp to Prevent Future Issues

Most long-term problems with resin lamps are preventable with simple habits. Our full resin lamp care guide covers this in detail, but the three most important points are: keep it away from direct sunlight (which yellows resin over time), don't leave it running for more than 8-10 hours continuously, and clean the surface with a soft dry cloth rather than water or solvents.

Storing Your Lamp When Not in Use

If you're moving, redoing your setup, or storing seasonal decor, resin lamps need a bit of attention to avoid surface damage during storage. The main risks are scratching from contact with other objects and direct sunlight if stored near windows. Wrap the resin piece in a soft cloth or place it in the original packaging if you kept it. A clean cotton pillowcase works as a temporary protective sleeve for most lamp sizes. Avoid bubble wrap directly against the resin surface without a cloth layer between them, as the plastic can leave marks under pressure over time. Room temperature storage away from direct light is sufficient. Resin does not require climate control for normal storage durations.

When to Contact Support

Some issues genuinely require follow-up from the store. Contact us if:

  • The LED does not light up at all on any power source
  • Flickering persists after trying a wall adapter and different cable connections
  • There is a large crack or structural void in the resin block
  • A bubble or flaw directly obscures the main figure and was not visible in the product photos
  • The lamp arrived with physical damage to the resin from shipping

When contacting support, include your order number, a photo of the issue, and a description of what troubleshooting steps you've already tried. This speeds up the resolution significantly.

Frequently Asked Questions

My lamp worked fine for months and suddenly started flickering. What happened?
Sudden flickering after extended normal operation usually points to one of three things: a degrading LED module reaching the end of its useful life, a loose connection in the cable or switch developed through regular handling, or a change in the USB power source (for example, a new USB hub or PC power setting update). Start by trying a different USB port and cable. If that doesn't resolve it, the LED module may need replacement.
Can I replace the LED inside the resin lamp myself?
The LED module connects at the base of the lamp via a USB cable. The cable and power module are replaceable without opening the resin block. However, if the LED inside the resin itself has failed, replacement requires workshop intervention. Contact the store for assistance rather than attempting to modify the resin.
Is it safe to leave the resin lamp plugged in overnight?
The LED components run cool and are safe for extended use. However, as a general habit, we recommend not leaving any decorative light running unattended for more than 8-10 hours continuously. Using the inline switch to turn it off before sleeping rather than unplugging it makes this easy. There is no fire or safety risk with standard use, but continuous operation does accelerate LED wear over time.
The resin has a yellowish tint. Is this normal?
Yellowing happens to all clear resin when exposed to UV light over time. If you notice yellowing shortly after receiving the lamp, this may be a natural characteristic of the resin batch used (some resin mixes have a slightly warm baseline tint). If the yellowing developed after months of use and the lamp was placed near a window with direct sunlight, this is expected UV exposure. Keep lamps away from direct sunlight to slow the process significantly.
There's a small crack on the surface of the resin. Is that a defect?
Small surface marks from the polishing process are considered cosmetic and normal. A crack that penetrates into the body of the resin block, visible from multiple angles and deep enough to affect the structural integrity, is a defect. If you're uncertain which category your issue falls into, send a photo to support and we'll advise you immediately.
Can I clean a dirty or fingerprinted resin surface?
Yes. Use a soft dry microfiber cloth and gently wipe the surface. For stubborn smudges, very slightly dampen the cloth with water only, no cleaning agents, solvents, or alcohol. Any chemical cleaner can cloud or etch the resin surface permanently. Avoid abrasive materials even for stubborn marks. If the surface has scratched over time from improper cleaning, a gentle resin polish (available at craft stores) can restore clarity.
