SLOW DOLPHIN Photo CFL Full Spectrum Light Bulb,4 x 45W 5500K CFL Daylight Photography Photo Video Studio Lighting(4 Packs)

Bought these replacement bulbs for my soft box lights and they’rejust what I needed!

Too expensive for lightbulbs but they work well.

Fast easy transaction

Pleasantly surprised about the quality of the product.

They work exactly how I expected them to. I didn't give a durability rating because it's too early to make that assessment.

Be sure to let these warm up before you start shooting, especially if you are taking handheld meter readings while setting up. From the time you switch them on until about 15 minutes later, there may be 4-5 stops difference in the light output. I plan to just turn mine on 10-15 minutes before I even start doing anything. They are reasonably bright, but not quite as bright as I thought they would be. Should be adquate to shoot with about any DSLR which does well enough at high ISOs. Durability is an issue I cannot yet address yet, have not had them long enough.

I love these light bulbs. I was introduced to these lights in 2012 for Photography and I have been using them ever since. They get very bright and last a long time. They also will generate heat when on so be prepared for a little cool down if you are in rooms and other closed in areas. I would highly recommend these for a lot of reasons besides Photography lighting.Hope this helps whoever needs to read this.

Not bright enough, even with all four bulbs it is not brighter than my Godox 80 watt continuous light. I'll have to buy a light source from the real pros at B&H

Llegaron a tiempo y los focos son de muy buena calidad
