What are Metal Halide Lamps? (Back to FAQS)

Metal halide lamps are part of a group of light sources called HID (High Intensity Discharge) lamps.

How do these work? (Back to FAQS)

Light is produced in these lamps by applying an electrical discharge through gas, metal vapour or a mixture of several gases and vapours. With metal halide, the major proportion of the light is achieved by the radiation from a mixture of various halides and a metallic vapour. The difference between low quality metal halide lamps and a high quality Venture lamp is the result of how well the electrical arc is managed, the electrode design, the blend of the gases and the forces on the glass on the bulb.

What Venture lamps are in the energy saving range? (Back to FAQS)

Energy saving lamps in the Venture range include 200W and 350W lamps which offer similar performance to the old style 250W and 400W lamps with definitive savings on running costs and the 450W version produces lumens almost equal to a 400W high pressure sodium lamp.

What does Venture’s energy saving kits comprise of? (Back to FAQS)

The Venture kit combines a lower wattage lamp along with control gear (i.e. ballast or ignitor)

What is an open rated lamp? (Back to FAQS)

An open rated lamp is for use with open luminaires i.e. no cover. For extra protection the lamp arc tube is surrounded by a protective quartz shroud.

What is an enclosed rated lamp? (Back to FAQS)

An enclosed rated lamp is for use with fittings with covers.

Why do we have 200W and 350W? (Back to FAQS)

Pulsestart 200W and 350W lamps perform to the same outputs as conventional 250W and 400W lamps respectively, resulting in 50W energy saving per fixture.

What is the lamp life of Energy Saving Venture Pulsestart 200W and 350W lamps? (Back to FAQS)

The life of all Venture Pulsestart MH lamps, including the 200W and 350W are much improved from the conventional MH lamps with up to 50% improved life.

Are 200W and 350W Energy Saving lamps available as Open Fixture rated? (Back to FAQS)

Yes, both 200W and 350W lamps are available in both tubular and elliptical / both for enclosed fixture and open fixtures.

What does "H75" mean on your Tubular lamps? (Back to FAQS)

The lamp is designed to operate in the horizontal burning position +/-75 degrees. This clever design means that for such as low-bay or floodlight application, you are not reducing the life or output from the lamp as you would with conventional MH lamps.

I didn't realise that conventional MH lamps suffered from operating them horizontally? (Back to FAQS)

Yes, this is true although not well publicised. Conventional MH lamps are rated for output and life based on vertical burning. Operating these lamps horizontally will reduce the life and output by up to 20%!

Do these lamps cost more to buy? (Back to FAQS)

The best answer to this common question is; 200W and 350W lamps provide a significantly less expensive solution to standard 250W and 400W MH lamps. Of course, you will read from this that the lamps themselves do cost a small amount more. However, the payback from 50W saving per fixture very quickly proves that this is by far the most economical solution.

How do Venture's energy saving 200W and 350W lamps perform against compact fluorescent? (Back to FAQS)

With significantly superior outputs. Lumen output efficiency is measured in lumens per Watt (efficacy of the lamp) & the efficacy of Pulsestart energy saving lamps is 105 lumens per lamp Watt. The efficacy of a high quality compact fluorescent is only 70 lumens per Watt.

This sounds too good to be true! Is there a compromise is there a catch? (Back to FAQS)

There’s no compromise and no catch! This is simply taking advantage of the best, latest MH lamp technology – available only with Venture Pulsestart.

How does Venture Pulsestart 200W compare to such as 4 x 54W T5? (Back to FAQS)

Like for like, with good a good fixture/reflector design – the 200W lamp will out perform the T5 system.

Are 200W and 350W the only wattages available? (Back to FAQS)

200W and 350W are the most popular, however 320W, 365W (Natural White), 450W and 875W lamps are available in elliptical designs.

Why 450W for example? (Back to FAQS)

An enclosed rated lamp is for use with fittings with covers.

What is lumen maintenance? (Back to FAQS)

Lumen maintenance or "maintained lumens" is a measure of how quickly the lamps output degrades over life. The Pulsestart technology vastly improves the maintained lumens of the lamp, allowing you to start with a lower lumen package from day one – thus achieving an even greater saving in energy.

What is Natural White and 365W? (Back to FAQS)

365W Natural White lamps are designated “950” (90+ RA and 5K). The resulting light being a brighter, more usable, greater visual acuity and with fantastic colour rendering. The 365W Natural White lamp is only 365W – but operates on a standard 400W MH (mercury) ballast – thus again, resulting in an energy saving of 35W per fitting.

Can you achieve further energy savings with electronic control gear? (Back to FAQS)

Yes you can. Ventronic offers a range of electronic control gear solutions – from 35W through to 450W – including all energy saving lamp wattage options. Further energy saving can be gained with careful scheme designs utilising dimming options available with Ventronic.

Are energy saving 200W and 350W Pulsestart lamps readily available? (Back to FAQS)

Yes - all Venture control gear and lamps, including Ventronic and the full range of our energy saving lamps are available from our UK stock.
