I figured I would share my experiences with my latest purchase. Its a Travor RF-550D (unsure where it is made but probably china) 48 led flash ring light. It has a led screen with a few buttons for selecting light or flash and flashing left or right on the ring as well as -1.5 to 1.5+ power settings. Mine came with 8 lens adpaters in various sizes to fit most lenses (49mm 52mm 55mm 58mm 62mm 67mm 72mm 77mm). As well as 3 diffusers (blue, yellow, frosted, clear). It seems to be built decently enough but the lens adpaters are made out of plastic so you have to be careful of over tightening and stripping them.
I purchased it for the light for my Sigma 105mm macro lens. I was sick of trying to hold a flashlight in one hand and using my other hand to operate the camera. It seems like it is going to work. I have not tested how long is lasts in each mode as far as battery usage I just recieved it about an hour ago. I paid $55.00 including shipping off ebay for the unit which I thought was a pretty good deal and it shipped from the US. The box says its made for a canon,nikon,panasonic,olympus dslr's. I will try and put it on my Macro lens and get some before and after pictures and see if it really works. I know leds have a bluish white tint to them so not sure what WB function needs to be used with them. Being a disabled vet I am on a pretty tight budget when it comes to my camera equipment so I have to try and get the most for my money. I just couldn't justify $200 or so for a pentax ring flash. Can't tell if it will last or not but I hope so.

| This looks pretty cool, and a good value at $55. I will be looking forward to seeing some how well it works for you and how it holds up. |

I've worked a lot with LED strobes built for industrial photography, they have some great advantages but also some drawbacks.
They are fairly cheap to produce, and usually very durable. They also tend to have more consistent color then standard xenon strobes. The downside is that they can't dump as much light as quickly as xenon. speedlite strobes can dump all their light in about 1/1000 to 1/10000 of a second. This LED flash dumps it's light in 1/100th of a second. It doesn't say how much light it actually produces, but it's probably not as much. Then again for macro work you don't need the crazy amount of light that normal speedlites produce.
LED's are fairly comparable to a speedlite in "High speed sync" for Canon or "HHS?" for Nikon. Instead of dumping a lot of light for a short period of time, it dumps a lesser amount of light of a long period of time. Not as good at stopping motion, but allows you to use any shutter speed. |

I was thinking of making my own, from flashlight lighters, and hooking them up to old rechargeable phone batteries. I still need to get the circuitry right... and buy all the lighters.

Just an update I used the led flash for about 2 hours today on a set of fresh alkaline batteries. Still working and have had no problems with it I used it to get 2 challenge shots and I am really happy with the results even though I didnt use the flash as I intended to use it.
Your also definately right  bhuge about a delay in the led's its definately noticeable and you can press the camera trigger and then pause about a half second for the led to discharge.
