The Shock and Vibration Resistant LED Bulb

A fragile lighting fixture above food under process is a hazard. It is an accident waiting to happen. Breakage might cause contamination to food with sharp glass fragments, electronic parts and poisonous LED solder. Due to this reason, regulatory bodies require lighting devices which could resist breakage.

So my hunt started.

First: Unbreakable Polycarbonate Bulb.

Second: The Cheap But Break Resistant LED Bulb.

This is the third installment.

The hardware store staff showed it to me before. They have LED bulbs that are shock resistant and almost close to unbreakable. Tapping the bulb enclosure against hard surface. No breakage happening and so I was not convinced. He was afraid of two things, breaking the bulb cover and damaging the internal electronics.

In addition, he opened an old stock led bulb made of glass enclosure. It was thrice as heavy and looked fragile. I am thinking their shift to lighter and more durable material is more of economy than safety. Glass is costly and takes so much energy to produce.

Today, I see the same brand confirming what their bulb enclosure is made of. They have a pack of four promo. Four individually packaged bulb is wrapped together with another labelled carton. It is clearly stated “enclosed in polycarbonate plastic”.

I grabbed one just for confirmation. Then, I found the following after careful inspection.

A dot size embossed in middle as sign of plastic injection molding. It is really made of plastic. Its brittle sound when knocked is subjective of polycarbonate nature.

I have the same brand in use at home. Same size, same wattage. It seemed they were built from the same material but latest appeared to have thicker shell.

I hardly knocked it against wood several times with no damage. I never did a drop test though. It might damage the electrical system including the aluminum base.

Unlike the cheap led bulb from public market, this is completely closed and sealed. Forcing it open may render it unusable.

In Omni web homepage, a video showing the advantages of LED bulb is playing in loop. One of them is durability. Animation showed it resisted a steel hammer strike.

It broke. See “The Unbreakable Polycarbonate Bulb Broke“.

Unbreakable Polycarbonate LED Bulb

The condition set by FDA guy to place all lighting inside protective cover or replace it with the new unbreakable LED bulb bothered me for a while.

Why ordinary are rejected?  In worse case scenario, bulb glass might break and contaminate food.  How bad broken glass is? I can inflict wound to outer skin easily what more to internals.

It is crystal clear that replacing the latter wins. Imagine the cost of light covers plus installation cost. On the other hand, just buy unbreakable polycarbonate LED bulb and replace the current. For flourescent light fixture, additional bulb receptable is very cheap and easy to install too.

Where can I find unbreakable bulb? I told my fried the story and he quickly replied with an answer. There is really a new kind of LED bulb and it is unbreakable. Public market vendors are throwing them on concrete floors and lighting them up to attract buyers.

From public market? I was getting the impression of inferior quality so I was not interested. Instead, I looked on local online store and found what I was looking for.


update as of June 18 2016:

I tried the cheap led bulb from public market out of curiosity. See article “The Cheap But Break Resistant LED Bulb“.


The brand that claimed to be unbreakable is made of polycarbonate plastic. If it is polycarbonate then it is really unbreakable. I have polycarbonate molding trays at home. They are unbreakable as far as my experience is concerned. I have been dropping them accidentally every now and then. Thankfully, no cracks, no breaks.

The price is almost double compared to ordinary LED bulb. It still outweighs the cost of protective cover and installation.

How about availability in local hardware stores? I tried several establishment but they all do not have stocks. I guess the technology is still very young. I also came across to large hardware store which the attendant entertained me well. He showed me the “shock and vibration resistant” words on label of one particular brand.

What he claimed is true. The bulb is light weight and plastic base. He gently tapped it several times on wooden shelf, no breaks, and light tested. However, the claim “unbreakable” is missing and he never dared throwing it down on floor. I never know what plastic it is made of but I felt like its gonna break with a bit stronger force than gentle tapping.

I tried the Shock and Vibration Resistant LED bulb of Omni. It works pretty well!
