They're probably around 2" long. I didn't realize that they were this small when I ordered them, but I've been really happy with them.

They are (from head on) 2.4mm X 3.3mm, including the larger part. The lens part that pops out is still 1.8 mm in diameter. This site has the dimensions. http://ledz.com/?p=leds.1.8mmFWIW, they are very bright regardless of package.

It is bright, very bright (and hot) but don't expect them to last too long... they burn out too quickly. Purchased these several times because of their brightness, but gave up reordering them because they are too pricey for the amount of time they last. (70 days tops in my numerous purchases) Good luck.

About 8 feet of lights. The battery unit is a foot from the light string. The lights are bright and the 3 AA batteries last quite a while. I was very happy with this purchase.

No. Sorry I was off mark in my previous response, I was inadvertently looking at wrong item. You get what you pay for. These lights just aren't wearing well and the sensor isn't particularly responsive on 2 of the 3 I purchased, and to the best of my knowledge, not distance adjustable. No worries tho; these def don't go 30 feet.

I have only ran them by hand, not on the bike yet. They appear to cast a wide beam and are very bright. If you look into them you will see spots for a while. They do not appear to shoot a long thin beam, bit will get the attention of anyone coming at you and will light up a trail very well. Ok, just went outside and touched the wires to my battery and the main part, brightest, of the beam is a good 4 foot wide at 20 foot distance. Hope that helps.

They are around 4.5" to 5" in diameter and about 3.5" to 4" high. And no, that version is not LED. I have used this exact strobe for a number of years and perform well for there price. Hope this helps.

I'm sorry, I can't tell you. I havent gotten them hooked up yet so I can't even tell you if I am happy with how bright they are. I'm hoping with that many led's in them that I won't be disappointed. I mounted them on the visors of my truck so I'd have a strong light right over me. You might get online to Amico and see if they can give some technical data for you. Sorry I couldn't be more help.

They are bright spot lights. Not dim at all. I have two under a big tree. Lights up the whole tree. Not sure of the width.

Well, nothing scientific, but they are blindingly bright. I can not look at the leds withput it hurting my eyes. The actual brightness will vary depending on the voltage applied. I don't know of anyone who had done an actual measurement.

They are close to 4 inches. They are very nice. Not very bright but enough light.

To be exact it is 4.5" across the head. And they are a bit heavy so don't use them in a long flexible fixture. But they are super bright!
