New PakCan Compatible with Welch Allyn 5 Pcs LED Replacement Bulbs 03100-U (Set of 5 pcs)

For the first time in 20+ years, I've had to replace the bulb in my handheld eye exam transilluminator ("muscle light"). Naturally I pulled out the bulb and ordered the same part number via Amazon. When making this purchase, I thought five bulbs would last me for life. -------------------------------------------------- My feedback: Not sure why, but I have been through 3 of the 5 bulbs in five weeks. Bulb works great for about a week, flickers for a few uses, then goes out. Each time I remove the bulb from the battery handle to replace, the metal contact point at the base of the bulb (corresponds to inside center point of contact on the handle) has fallen of the bulb. My previous (25 year) bulb was 03100 and this is a 03100-U so perhaps I'm at fault. My impression is they are interchangable but perhaps these bulbs aren't in which case don't repeat my mistake. If they are interchangeable, I'm at a loss to explain. Perhaps it might be a fluke bad batch of bulbs?.?.? My apologies to the vendor if it's my mistake. I'm leaving this feedback just as an FYI for others. ------------------------------------------------- Observation: The -U model is certainly brighter and "whiter" light from the LED wavelengths (vs my original factory bulb).

Buen precio

all dead within 1hour to 3 days - do not buy. One was dim from 1st use then started flashing on day 3 then died. Others worked for a few days - approx 10 minutes use per day then just died. All 5 have failed. Obviously faulty product.

Life of light bulb

We have used 3 of these in less than 2 days because they burn out very quickly. They are definitely not the same quality as the original bulbs.

As described, good price, fast ship.

These blow out within a month. I am down to one bulb left after buying 5. My welch allyn bulbs would last years.

Didn't realize that these were LED, but after reading all of the reviews, I realized that wasn't he only mistaken I made. They're bright, but not as bright as the halogen. Their hue is definitely much cooler and almost blue instead of the incandescent that you'd expect for an otoscope bulb.

None of the 5 light bulbs in the pack were working. I contacted the seller for a return/ refund and no resolution yet. Do not bother to order this product, it is either defective or not compatible as advertised. Very poor response from the seller to my complaint.

Muy mala calidad en menos de una semana ya no prenden dos focos, yo tengo otro equipo y ya cambié y todo funciona bien, son los focos los que fallan, y pues bueno yo tengo la culpa por comprar barato.
