Rating: Big Blue CF900P L.E.D. Light Review - Scuba Gear Customer Reviews
Reviewer: Chris M.
Not very happy! First of all, when i received the light there were no battery or charger in the box. Just the light. So, I called customer support and they said they would not refund me until they got that light back. I was ok with that. So, I went ahead and purchased another light. $200. It took them over a week to refund my money after they got the light. Also over a week before i received the new light!! As far as the light!! Seems to be a nice product!

Batteries do not last as long as advertised.Light goes dim well before it runs out. Square beam is a little annoying.

Questions and Answers for Big Blue CF1000P L.E.D. Light:

  • Peter:

    Sellers like 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 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.

  • franc:

    is this good light under water, I am buying as a gift, I do not know much about it

    Aaron  (Certified Scuba Instructor at

    Hi Franc Big blue makes a great light. With 900 Lumens it is a really bight light. It will make a great gift.

  • Jim:

    Please clarify what batteries are used with this light?

    Bill  (Certified Scuba Instructor at

    This uses a 18650 Li ion rechargeable battery.

  • eric:

    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

    Bob  (Certified Scuba Instructor at

    The mfg does not offer the external dimensions of the light. Looking at one here today it seems like it would fit in the glove, although the length of the body of this light would make it not the most comfortable light in the glove.

  • Russell:

    Does the light come with a recharging device for the battery?

    Darrick  (Certified Scuba Instructor at

    Hello Russell, yes it comes with the recharger for the battery.

  • Pete:

    Is the battery charger that comes with this light USB based so it can be used anywhere in the world? Or is it US 110V only?

    Darrick  (Certified Scuba Instructor at

    Hello Timothy, not this charger is rated for 110v. If you are going to use 220v you would need some type of power inverter to charge this off of a 220v plug.

  • ANA:

    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?

    Darrick  (Certified Scuba Instructor at

    Hello Ana, you would need to take the battery out of the light and put it in the charger to charge the battery.

  • ANA:

    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

    Darrick  (Certified Scuba Instructor at

    Hello Ana, no longer carry the aqua seal.

  • Josh:

    Another review states that the lumens peak around 90. I am interested in the light but want to know if that is the previous model put out. What is the actual light output?

    Darrick  (Certified Scuba Instructor at

    Hello Josh, this lights output is adjustable from 90 to 900 lumens.

  • Ben:

    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.

    Darrick  (Certified Scuba Instructor at

    Hello Ben, the set-up you would need you can find at: you would need this piece and the two other pieces also to mount your light to your camera.

  • Virginia:

    Hi, Im looking for a spare battery for this light - do you carry it? Urgent for my order please and thanks in advance! Virginia

    Elliott  (Certified Scuba Instructor at

    Yes we do! Item: Sealife Tenergy Li-Ion Battery Battery

  • Jean:

    Can this light be used for short periods on land, or is there a heat issue? There is nothing marked one way or the other in the manual.

    Arthur  (Certified Scuba Instructor at

    Hello, yes it can. LED lights don''t generate heat like traditional lights.

  • Lee:

    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?

    Darrick  (Certified Scuba Instructor at

    Hello Lee, yes it is possible to under screw the light when you are under water. But if all you are doing is turning the light on and then adjust the beam no you will not unscrew it to where you will flood the light.

  • Tom:

    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

    Darrick  (Certified Scuba Instructor at

    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. .

  • James:

    I own one Big Blue Light and plan to purchase this one. My question is does carry the replacement O-rings for the lights? I would like to have back ups. Thanks

    Arthur  (Certified Scuba Instructor at

    Hello, no we don''t carry spare O-rings for these lights. Big blue is very good about helping out customers that have purchased their lights and would be able to help you out.

  • Tamás:

    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.

    Darrick  (Certified Scuba Instructor at

    Hello Tamas, yes are description was wrong and we are having it changed as I type this to the correct description. But this is the most current model of the light.

  • Csaba:

    I try to find out which bulb is used for this dive light. Does it have CREE XM-L (XM-L2 T6)? I cant seem to find any exact specification. Thank you.

    Arthur  (Certified Scuba Instructor at

    Hello, try contacting Big blue directly for details like this (585) 749-1998

    Csaba  (Customer & Owner of this Product):

    I dont live in the US, this is why I asked here. Thanks anyway.
