Dan, what is the suggested burn time of the current light? How about the two new options?
To me, I can't imagine a light too bright. I always want to be able to see deeper and clearer. I don't have an issue with changing batteries a lot. I like rechargables.
One suggestion. Look into the lights that take the bigger batteries, I think 18425 is the size. They are much beefier cells than a AA but don't weigh as much as a C. Ill look up the actual name and post it later.

Could be 18650? there's also it's big brother 26650...
Much better then having to insert/charge/handle a bunch of batteries.
For day time spearing (the only allowed here) burn time is not an issue (very short intervals that it's on to look into caves) and having a rechargeable makes it a non issue...
I believe that there's such thing as "too bright" but haven't experienced it yet 
And 270 shouldn't be too much
I just went to the store site and looked at the light, even in the day light that thing looks bright and a 8 hr burn time is all I ever need. Dan do you still have the light in stock?
Cheers, Don
Night diving/spearing is allowed in DK - a lot of us are using these...

No such thing as 2 bright... I have always found that the lights I use for holes, dont do the job well enough. But maybe the problem was not the lights but my unwillingness to pay 760 euros for a light!(I would have trouble paying that for a gun!) :laughing: That's one sweet light though!!!
You guys got to start a thread on how to run a thousand US dollar flash light past the wife :laughing3:

I don't know answer to the question of "ideal brightness" but I too use the IFL660 for peering beneath ledges or into holes during daytime. I carry it clipped to my belt. I like its compactness and the intensity of its narrow beam. My only complaint is that it doesn't have a lock to hold the switch in the off position. A couple of times the light has turned on inadvertently while on my belt, or in my gear bag, and run the batteries down. I'm gonna try to fabricate something with ShapeLock to remedy that.
For those of you that don't mind buying used gear, the light sells for $25 at Intova's website.

It's odd, but I notice the specs listed differ a bit between Speardiver, Intova (new) and Intova (used.)
Speardiver shows: 220 lumens; 8 hr burn time; and 12 degree beam angle
Intova (new) shows: 300 lumens; 3 hr burn time; and 7 degrees
Intova (used) shows: 130-220 lumens; 5 hr burn time; and 7 degrees
(I think the 130-220 lumens must be a typo.)
For sporatic on/off use during daytime, the batteries last a long while. But for continuous use during night dives, you probably want to put in fresh batteries after a couple nights of use. I don't like having to buy the CR123 batteries that frequently ($$$).
For years, my night light of choice had been UK C4 eLED. But this past year I got an Intova SL1. Now that's a BRIGHT LIGHT! Advertised as 800 lumens, 7 hr burn time, and uses 3 "C" batteries. (Much more affordable than CR123.) I mostly use the light at the reduced power setting and it's still plenty bright. Intova sells the SL1 used for $80. SL1 Search light | Intova

Holly shite !!! but no gun needed...just light saber them in half.:@

For simple day time hole searching, my 130 lumen light is more than enough light. I dont think brighter is always better in daytime conditions. Night may be a whole other ballgame though.
My favorite lights have been 220 lumens. All of my hunting up to this point has been in holes during the daytime. The real difference is in the width of the beam. Too broad and it won't penetrate into a crack deep enough to make out a fish, to narrow and you may miss the fish doing your sweep. I think it is a balancing act.
