Sunlite BTL 500W/T6/120V/CL/P28s 500-watt 120-volt Medium Pre-focus Based Stage and Studio T6 Bulb, Clear

Used as replacement for spotlight for church program. Light was perfect for the concert we were recording.

Exactly what we needed in the school gym.

Good price, works as needed

I bought 3 of these because I could get them FAST. ALL 3 BURNED OUT WITHIN TWO DAYS. Believe the other reviews! These bulbs are JUNK.These bulbs are worse than having nothing, because you THINK new bulbs will survive for a few shows (at least), but then they blow half way through first or second show, and you look like an idiot.In case anyone like SUNLITE thinks we had high voltage issues, shock & vibration, dirty fingers on capsule, etc., etc... NOT! This wasn't our first day on the job. We simply used them in stationary, Altman ellipsoidal spotlights to illuminate billiard tables during a tournament. AND, we have had normal performance from lamps by OSRAM and USHIO before and since. But, one day, we needed 3 more bulbs FAST, and Amazon had these SUNLITE brand bulbs to us SAME DAY (love Amazon, hate Sunlite).Burn your money before you order these bulbs.UPDATE: 3 months later, the OSRAM bulbs that replaced the junky SUNLITE bulbs are still burning bright.UPDATE: 1 year later, and two sets of OSRAM bulbs later, and we got nearly 2500 hours per bulb (rated at 2000 hours). OSRAM rocks!

Light buld wirks but it don't lock in with the twist. I have 1940 bell and howel Projector, I guess I have to take what I can get. But it does work.

Had two of them burn out in the first two weeks, not sure if it was the light fixture or the bulbs, but one of them got really hot and burned up the socket (I have to replace it). Will not buy this brand again. Stick with GE, Osram or Ushio have had good luck with them.

Had one burnout really quickly, could have been user error.

Bought nine of these in June 2017, installed in Mid-July, seven of the nine burned out within two weeks or 24 hours of use. JUNK. Of course it was after the returned date had passed. Not only cost of the bulbs was lost but the cost of the rental of a lift for installation. These items should not be offered by Amazon

great!

Excellente ampoule de remplacement pour projecteur 8 mm Bell & Howell

Purchased 3, first two in two different fixture (fresnel 500) lasted about 5 and 10h respectively. All direct contact with the glass was avoided). Just put the third one in now, we will see how long it last. Very disappointing!

Good solid lamp

had to replace around 12 light bulb for stage lights. Fast shipping and fits perfectly at a reasonable price.But they seem to have a durability issue after 2 weeks of replacement 3/12 bulbs had already worn out.( The bulbs are only used twice for 2-4 hours a week)
