EiKO EBW Blue Inside Frosted Light Bulb (Pack of 2), 120 Volts, 500 Watts, 4.17 Amps, Medium Screw (E26) Base, PS-25 Bulb, C-9 Filament, 6.10"/155mm MOL, 3.15"/80mm MOD, 10500 Lumens

I purchase on June 18 for use while recording church sermons and 1 of the 4 just blew out today. Two bulb were in use in separate light sockets. I installed them every sunday with clean gloves to prevent dirt and oil from getting on the bulbs. According to the package each is good for a minimum 6 hrs but it didn't last more than 2hrs

I've tried many blue 500 w floods, and found these to produce the best color spectrum. I use them to shoot fine art. Did not have any breaking shattering issues at all. Glad I found these!

I use them to burn in the image for screen printing. They work great!

I use these to light subjects when I need to supplement natural window light. I set my white balance to daylight, and the skin tones look very nice.

Ordered two bulbs, the first one burnt after less than an hours worth of use, pretty disappointed as these are pricy. Hopefully the second one lasts longer.

We use these lights for taking photos of items that I sell and they help produce a realistic color.

I only received 3 of the 6 bulbs from the ordered pack.

The 500 watt blue daylight bulbs provide true white light! I always reorder these, and they work very well!
