Question: Which Bulb can i purchase for this lighting kit?
Document: This is a great lighting set for a beginner like me and has started working wonders from the moment I started using it! I feel I won't need to update for a good, long while. The only -problem- with the kit is that the light stands are very flimsy. I will end up replacing those soon.
Package arrived within estimated time. Products were in good shape and performed as expected. The materials for the soft boxes were made poorly and already require reinforcement. All around, this was a solid purchase but the materials must be handled lightly.
I was skeptical after I read other reviews but I'm extremely happy with the purchase. I am a professional photographer with a small studio. Budget is very important to me but smart purchases are even more important. Others have been critical of the versatility of these lights but I am very pleased with their performance.Pros: Wireless function works perfectly. Fast recycle time. Nice, even, soft light when using the soft boxes. Controllable hard light when you choose not to use the soft boxes.
This is a great starter kit! Great if you are just getting into studio photography. My thoughts on each item:The strobes worked fine .. nothing much to say here untill i have had them alittle longer to see how they perform. It comes with some long power cords. you shouldnt have a issue plugging them in where you want.The package comes with 2 umbrellas and 2 softboxes which was in perfect condition.
Nice starter kit,make sure that you confirm receipt of carrying case.Light stands are too light for "this kit" will need some weight to remain steady. can  easily fall, if fully extendedAlso,two out the three stands were stuck upon delivery and unable to open/expand unless forced with the use of pliers etc...which happens repeatedly when collapsed.
Greetings to you all, I am a customer of you receive from me a cordial greeting, I am writing this letter to inform you that I am very happy with the product you buy them! It is of excellent quality and professional, now would please review their inventory and not included in the shipping kit soft box two (2) announced at the sale, I expect a prompt response thanks for your attention.

As a photographer I'm getting more into studio and i was looking for a cheep kit i can travel with. I got this kit thinking it will be ok for the price. And I will have to say I was amazed! you get a great product for the price you pay! Only down side i wish it came with 3 wireless triggers for all the flashes. & one of the flashes moon light control is a little stiff but works.
I am very happy with this studio light kit. It has worked great so far, no problems. The materials are not top quality but again, you're not paying top dollar. However, the set once it is all put together looks great and unless you care about every little detail, the lights work and give positive results. I have yet to use the gels and umbrellas but that wouldn't add much more to this review.
the material that its made of is not good and not strong enough. 2 days later that he received the package, i was going to use one of the stands to take picture. but it was broken. i almost lost the light itself. not good
They were shaped differently but they still fit and im pleased with the quality of the bag. All my items fit in the bag with no issues.Overall this package is a great deal.
