Apparently you do have to tell me twice. A few monhts back I fried my SB800 at a ballet show. The top plastic lens had bubbles melted into it because I shot so much in succession with it. Fortunately it was under warranty and I had it fixed for free.

Well I had another show 2 weeks ago and I went to use one of my SB600s for the first time since than and it wouldn't turn on. Odd. I take a look and sure enough... I melted another one :(

This time it's out of warranty so probably not worth even trying to get fixed. You'd think I'd have learned my lesson the first time but OH NO, NOT ME!

So be warned - Nikon flashes can only take repeated flashes only so long before they start to melt.

dang I need some studio strobes :(

That blows lol I use the flash on my P&S in continous drive all the time with the power down to -2 its 1.9 fps is reduced to about 1.5 fps.

If i ever get an dSLR thats definatly something id be doing lol. And id be melting them worse then you.

By the way Ken Rockwell already covered this maybe not such an idiot? LINK

"Do this a lot for a long time and you may be able to melt a flash unit. Just feel the front of it now and then and back off if it's getting too hot. Nikon specifies in their user manuals how many full power dumps you're allowed and how long you have to wait for cooling without melting the flash. I find I can do much more than that and my flash still works. I don't worry about this, but I'm not shooting pro sports all day long either. Just be careful."

Then again he does sound like an idiot......

yea, the manual does say how much and I tried to be careful both times but I use a sto-fen on my flashes when they are set up remotely and I have the close up filter down (to hold a gel in place and to spread the beam as much as possible. This combination traps the heat and melts it much faster. I knew better and still ended up doing it. Trust me, I'm an idiot :P

I can't believe they don't have protection against this! I was recently doing some flash tests, and was taking shot after shot after shot with flash. Fortunately the camera stopped me from taking too many photos. With out it, I would certainly have fried my flash several times over! Do they think that maybe pro photographers might want to take one last shot that is worth frying the flash for, so they don't protect it? :)

This meltdown happens a lot for almost all flashes if a lot of flash in a short time period. Even more if you use some of the flash bubbles or diffusers such as the one by Fong and friends. There is a lot of heat buildup on each flash activation. In most situations such as a wedding there is several seconds between flashes and should not be an issue but if you are there to take a million pics and keep a few good ones be careful.

ARRRRGGGGGGHHHHH!!!!!
WEnt to do another quick shoot tonight with my last remaining sb600 (nothing big just a dozen photos or so) and it turns out it's broken as well. It turns on but it says "low bat" immediately and then shuts off no matter what batteries I put in it. grrr!!!!

Now I have a huge poster shot on Wednesday (my biggest ever) and only 1 flash. This is bad :(
