A study by the State University of New York at Stony Brook revealed that manufacturing flaws in some compact fluorescent bulbs can lead to potential UV exposure. The study, published in the scientific journal Photochemistry and Photobiology, reveals that tiny bald spots in the phosphor coating in compact fluorescent bulbs allow UV light to escape.
Researches say that compact fluorescent bulbs are prone to cracking due to the manufacturing process, which causes cracking in the phosphor coating while the bulbs are twisted into the familiar curlicue shape. The research is still in the preliminary phase and hasn’t been tested outside of the lab, which means that there haven’t been any known cases of sunburn caused by compact fluorescent bulbs, and researchers say that avoiding the UV exposure isn’t difficult.

You might be getting some UV exposure long after the sun goes down — some new fluorescent light bulbs give off UV light. If you are particularly sensitive to UV, then select CFBs that have a double envelope instead of single, as it will block most of the UV light.
Also, remember to sit back from your TV (which my mother taught me to do when I was a kid).
Actually you SHOULD switch back to the energy wasters because in the long term those ones are BETTER for the environment! Trust me, the old fashion energy wasters are WAY “greener” then these curly lightbulbs of death! I use the curlies for the bedroom cuz the ceiling is 9 feet up and I don’t have a ladder.
I’m thrilled to see so much discussion about energy efficiency, whatever the opinion.
How about led bulbs and tubes?Although expensive LED bulbs can produce light that is comparable to incandescent. LED (Light Emitting Diode) last longer that compact fluorescents, they use less energy than traditional bulbs and potentially, compact fluorescents.
Xander is right–eventually switching to LEDs will be the smart move, but there are a lot of impostor companies selling today. Apparently there are now these decorative panels that you place in the fluorescent lights, and it acts as a filter from that harsh lighting.


I disagree with Jami and the rest that beleave that flurecent are very hazardious when you reak one. This item will be shipped through the Global Shipping Program and includes international tracking.
Will usually ship within 1 business day of receiving cleared payment - opens in a new window or tab. 1.The item must be returned in original resaleable condition with all tags and packaging (ready to be put back on the shelf). 4.The refund would be processed after the item is received by our warehouse staff, which is confirmed to be unopened and in good condition. Compact fluorescent bulbs, which have become popular in recent years as the result of new federal efficiency standards, are an energy-efficient alternative to the common incandescent bulb.
While fluorescent bulbs have always produced this UV light, which is emitted by the mercury vapor comes in contact with an electrical current, it is usually been absorbed by phosphors which make up the powdery white coating on the inside of the bulb.
Staying a few feet away from the bulbs or keeping a piece of glass between the bulb will eliminate exposure risk. Some of you are just ordering professional made PCBs, that is not always worth of cost, other are using easier way – Laser printer toner transfer technique which is not very accurate, third option is more advanced – ultraviolet light exposure of photo-resist coated PCB through film mask. Auto immune diseases such as lupus, inflammatory disease such as rosacea, and certain drugs such as HCTZ can be triggered by even small amounts of UV light from CFBs.
Of course, now with HDTVs, you get the best picture when you’re sitting a distance of 3 times the diameter of your TV. As an energy-efficient lighting vendor I’ve found the best method of increasing awareness is simply informing my consumers about the latest products.
I’m now thinking of getting one of those personal UV monitors as a way to check but I need to find out which band(s) they test. UVA-340 offers the best correlation to outdoor exposures because it is the best simulation of sunlight from 295 nm to 365 nm. Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag. But due to manufacturing flaws, they could expose skin to the damaging effects of UV light, potentially leading to skin cell damage and possibly cancer.


Further study is necessary, and other energy-efficient bulbs, such as LED bulbs, don’t appear to pose the same risk.
If you just bought a 60 inch HDTV, you might need to be in your neighbor’s living room to watch it.
The fact is that when they purchase energy efficient CFL or LED light bulbs they do see the savings on their energy bills. If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. The coating prevents most of the ultraviolet light from reaching you, but not entirely; some UV radiation leaks out of any fluorescent bulb.
The amount of UV exposure that you get from the light bulb is small compared to the UV exposure you get from just being outside; for most people it is not significant.
There is a lot of discussion about government mandates and whatnot; while this does benefit my business, I think simply selling the newer bulbs on their own merit is the best way to go. I don’t use a single incandescent light bulb any more…well ok, I have one in one of my flashlights! In some CFBs, the emission of UV light is so high that it exceeds the safety limits of the International Commission of Non-Iodizing Radiation. My parents are somewhat wary of fluoros as they still associate them with the old flickering magnetic ballasted tubes (they definitely caused headaches in some people).
You need to shop around for decent brands and pick the right temperature (colour) CFL for the location eg. Also you should select a CFL with a higher wattage than what the packaging states is the equivalent incandescent as they overstate the CFL’s equivalency, plus CFLs lose brightness over the years. As embedded part of this project is a count down timer with LCD built on AT90S2313 AVR microcontroller which can be replaced with newer ATtiny2313.

Comments Uv exposure bulbs keep

  1. SERSERI
    Fair with yellow undertones in my skin, many colors looked too uv exposure bulbs keep percent of the sun's UV rays.
  2. RAMZES
    Pressure UV provides light with monoxide and VOCs 72 73 74 UV lamps radiating at 184.
  3. BRATAN
    Used for 2 to 8 weeks Does what coating will completely defend.
  4. KRASSAV4IK
    I'll get a bottle of PVA glue.
