Since i am writing my unbiased opinion in spite of getting these products at a discount i must say i dont like the leds

On a final note i read reviews prior to the purchase that these lights are unreliable and dont always work

The only issue i see is that both top and bottom by the clicker switch and by the bulb needs to be well screwed in

I can shake it a little and it works its just frustrating

Received black green and silver overall the light output is strong maybe a bit too strong for pupillary responses but it can be circumvented by not shining the entire light into the eye

I work as an emt and i needed a better pen light for my patient assessments i was very hesitant to order something that was from china but for me i was willing to take the chance after all its not that much money
