Review: Worth the money upgrade for lighting kit - I purchased one of the 600 watt light kits that come with 45 watt spiral bulbs, these bulbs are vastly better. Larger size (big honking bulb!) and much stronger output. I tested as follows. Ambient light was living room at night with a couple of table lamps and light in the next room on. The low ambient light better allowed me to see light range and distribution. Important measurements to me since I plan to use these to shoot group photos. Using the 33" black/silver reflective umbrella from the kit at approx. 20 ft. with ambient light requiring 1/30 second shutter speed this bulb allowed for a better evenly lighted picture across approx. 15-18 ft. at 1/60 shutter speed. The 45 watt only had about 12 ft. of reach and at that range was just barely allowing 1/50 second shutter speed. Whatever the small 45 watt bulbs can do these KAEZI 85 watt bulbs will do better. Big light on subject is better than small that is why people use diffusers such as umbrellas. The sheer size of these bulbs makes them a big light source, Brighter light is also better than dimmer so I think these bulbs are good on both these key metrics. I look forward to testing with a 60 inch shoot through white umbrella and 53 inch reflective. The 5500k color temperature of these bulbs is also very close to my flash units which I use on camera or on stands with remote trggers. This will make getting a good white balance easier than a 6500k bulb would. I have used remote triggers and flash before purchasing continuous lights and am glad I will have the option of also using the flash units at the same time as a supplement. Or as backup if a fluorescent bulb fails at a bad time. One thing to watch out for the size of this bulb puts it close to the umbrella shaft, umbrellas bounce a bit when moving the stand. I would advise using care to make sure the shaft does not smack the bulb and possibly break it when moving stands around. So a triple win. Big, Bright, and color temp matches flash units. Only thing left is bulb life and if they fail in the first few months I'll update the review. Review: Nice and big light. - Please watch my video review for a closer look... As many other reviewers, I had one of the cowboystudio lighting kits. Unsatisfied with the lighting power of the 45 watt kit light bulbs, I decided to invest in one of these 85 watt bulbs. I was initially undecided about getting this ones or the 105 watt ones. Finally I decided to go with the 85 watt ones considering the good reviews and price. And I'm glad I did. This light bulb provides a much brighter, powerful and clearer white light than the 45 watt option. The light is good enough that I can light up almost my entire basement with a single bulb. I am considering getting another one to use in my garage. Here is my list of pros and cons: Pros: - Strong and powerful light. - Bigger light. Has more reach. - Very pure white. - Good materials. - The box that it comes in is very good and keeps the light bulb safe. Cons: - The light bulb is very big and might be difficult to use with some modifiers such as softboxes. ## Features - Long bulb life of appr. 6,000 hrs. - Dimensions: L: 10.5"; W Diameter: 3.9"; Length socket base to top of ballast: 4.5"; W (diameter) of socket: 1". - Daylight color temperature of 5500K - Super bright with 4250 Lumen @ 1m - Standard USA E26 base screw-in sockets ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00BISL11U | | Accepted voltage frequency | 100 to 120 Volts and 60 Hertz | | Average Life | 6000 Hours | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #91,444 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #107 in Compact Fluorescent Bulbs | | Brand | Kaezi Photography | | Brightness | 4250 Lumen | | Bulb Base | E26 | | Bulb Length | 10.5 Inches | | Bulb Shape Size | F10 | | Color | Daylight White | | Color Rendering Index | 4800 | | Color Temperature | 5500 Kelvin | | Control Method | App | | Customer Reviews | 4.4 4.4 out of 5 stars (673) | | Date First Available | January 28, 2011 | | Efficiency | Average | | Incandescent Equivalent Wattage | 300 Watts | | Indoor/Outdoor Usage | Indoor | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 0.01 ounces | | Item model number | 85W-BULB | | Light Color | Daylight White | | Light Output Maximum | 4250 Lumens | | Light Source Type | CFL | | Light Source Wattage | 85 Watts | | Light Type | CFL | | Manufacturer | Kaezi Photography | | Material | copper | | Number of Items | 1 | | Part Number | BULB85W | | Power Consumption | 85 Watts | | Power Source | Corded Electric | | Product Dimensions | 3.9"W x 10.5"H | | Shape | Spiral | | Special Feature | Not Dimmable | | Special Features | Not Dimmable | | Style | Modern | | UPC | 845484005321 | | Unit Count | 1.0 Count | | Voltage | 117 Volts | | Wattage | 85 Watts | | White Brightness | 4250 Lumens | ## Product Details - **Brand:** Kaezi Photography - **Bulb Shape Size:** F10 - **Light Type:** CFL - **Special Feature:** Not Dimmable - **Wattage:** 85 watts ## Images ![KAEZI 85 Watt Studio Light Bulb 5500K CFL Day Light. - Image 1](https://m.media-amazon.com/images/I/31ZerWoAHaL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worth the money upgrade for lighting kit *by T***I on October 11, 2014* I purchased one of the 600 watt light kits that come with 45 watt spiral bulbs, these bulbs are vastly better.

They are well packed and all look to work right. I purchased them to replace the 45 Watt bulbs in my Reflecting Umbrella photography lights because the 1 x 45 watt is ridiculously low. You have to practically stand directly in front of the light. Just never been bright enough. These are VERY bright and that's great but WARNING. These bulbs are about Double The Physical Size of the 45's and barely fit the stands I have. They screw in properly, but the stem of the umbrella is a fixed distance and the bulb actually touches it. They don't heat up fast and I think it will be OK for my use...short durations. But be aware of the size if you are moving up for wattage. In my photo the original bulb that came with the kit is on the left. ## Frequently Bought Together - KAEZI 85 Watt Studio Light Bulb 5500K CFL Day Light. - SLOW DOLPHIN Heavy Duty Spring Clamps Clip 4.5 Inch for Muslin/Paper Photo Studio Backdrops Background-6 Pack(Black) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/1747504-kaezi-85-watt-studio-light-bulb-5500k-cfl-day-light](https://www.desertcart.co.uk/products/1747504-kaezi-85-watt-studio-light-bulb-5500k-cfl-day-light) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-21*
