Sellers like scuba.com should really take Big Blue to task on their chronic over-stating of run times - usually by a factor of 2 or 3. I emailed Big Blue about one of their lights (VL5800P), and questioned how it was even possible to get the run times they state for their battery/led combinations (Ive made a couple scuba lights, so I know what is possible). They didnt even respond. This light will get a max run time of about an hour (likely less) on one 18650 battery pushing an XML LED at max 900 lumens - that is it. Note that on the Big Blue website, they list the run time as 2 hours on high for this light (not possible), and scuba.com lists it at 2.5 hours (even less possible). Buyer beware.
Hello Peter, thank you for finding errors in the description. I am having our IT dept. contact the manufacture to get the correct description. As for the burn time of the light. I use the Big Blue TL2500P light and have never had an issue with the burn time of these light. But I do adjust the different light outputs for the type of diving I am doing.
What are the dimensions of that light and would it be compatible with wearing it with the Big Blue light glove mount? Thanks in advance for your info
Hello, I want to be sure: by rechargeable it is correct that you do not have to open de light to change batteries, you connect it to the recharge accessories. I understand correctly?
hello i just send a question about a light and i do not know if i was looking to a specific product if you know which one i am talking about. it is de big blue cf900p l.e.d. light. i would also like to know if you have the mc-nett seal aquaseal to repair the wet suits. thank you. ana
Im looking to use this light for some video as well as a general dive light. What is the best way to mount this light to my camera rig? I looked at the Bigblue website but I didnt see a clip or band made specifically for this light.
Hello Ben, the set-up you would need you can find at: http://www.scuba.com/scuba-gear-615/025148/Light---Motion-Locline-Light-to-Arm-Adapter.html. you would need this piece and the two other pieces also to mount your light to your camera.
Is it possible to flood the light when adjusting the beam focus? put differently, can you open the front end of the light accidentally when adjusting the beam spread?
I just received my cf900p from you this week and it flooded on the first dive. But only the front chamber. I noticed bubbles coming through the little screw that is present at the chamber in front of the led. The manual gives no instructions as to what this screw is for. It has no o-ring so cannot be expected to keep water out. What is the issue here? The box with the light also contained an extra one of these little screws. Please advise before I send this back (not very happy to put it mildly). Thanks, Tom
Hello Tom, The Bigblue CF900P comes with a spare set screw and many have asked why we include this. In 2009 Bigblue first introduced focusable LED Dive Lights. We found that it was important to give the user the ability to take off the Lens shroud and clean out fine grit/sand particles that at times get underneath the lens shroud. The user is to rinse the light with fresh water with the shroud off. The set screw on the side of the shroud keeps it from coming off during normal use. When the need arises to remove the shroud the screw needs to be removed by unscrewing it. This screw being very small, is easy to lose during the cleaning process. The spare screw is provided simply as a spare in case the original is lost since it is relatively unique and would be difficult to replace. Some have suggested that removing this screw floods the lens cap and cools the LED. This is completely untrue and in no way does the manufacturer recommend removing the screw and then diving with it off. It is only to be removed during the cleaning process and replaced. .
I own one Big Blue Light and plan to purchase this one. My question is does Scuba.com carry the replacement O-rings for the lights? I would like to have back ups. Thanks
Im confused : is this the cf900p or the old cf900? The new one gas the push button as on the picture. But in the description it was mentioned that it has a rotary magnetic switch, like the old cf900. Couod anyone clarify which model is this? The latest one, or the old one? If its the old one, then the product title, code has to be changed. Thanks.
